Teams rarely leave Engine over the bill, because the booking platform is free. They leave for something specific: a paid add-on that turned out to carry a real price, a rewards ladder that only pays properly at a spend level they will never reach, or the realization that somebody in the company still spends hours a week inside a booking tool.
Engine (formerly Hotel Engine) is a corporate travel booking platform. An administrator sets policies and budgets, employees search and book inside those rules, and the charges land on one consolidated invoice instead of scattered across personal credit cards. For field crews, project teams, and anyone moving people in volume, that shape of product works, and the core platform costs nothing to use.
This page covers the alternatives worth a look, Catch included, though Catch is not a booking platform at all. It is an AI Executive Assistant that takes admin work off an executive’s plate, and business travel is part of that work: it books the flight and the hotel from calendar and email context, then keeps managing the trip afterwards.
What Engine Is Now, and Why Hotel Engine Reviews Describe a Different Product
Start with the name, because it changed. Hotel Engine rebranded to Engine, and the product grew past lodging at the same time. Alongside hotels, the platform now books flights and rental cars. Search demand still sits on the old name, which is why most Hotel Engine reviews you will find describe a product that no longer goes by that name.
What the platform sets out to do, it does. Administrators can set custom travel policies and budget controls in the platform. Direct Bill pulls company travel charges onto a single consolidated invoice. Engine can cover hotel incidental holds upfront and route those charges to the corporate invoice rather than leaving them parked on a traveler’s personal card, which matters more than it sounds like it should for field workers who cannot absorb a large hold. Group booking is a real specialty: Engine provides dedicated support and a purpose-built interface for trips needing nine or more rooms or extended stays. Travelers can also enter their personal loyalty numbers and earn standard hotel loyalty points alongside Engine’s own rewards program.
The pricing claim holds up too. Engine’s own pricing page states the platform is free, not a free trial, with no membership fees, no contracts, and no minimum spend. What costs money at Engine sits next to the booking platform rather than inside it, which is where the next section starts.
Three Reasons Teams Start Shopping for an Alternative
The extras are where the money is. The booking platform is free. What sits next to it is not, and it is priced for companies rather than for individual trips. FlexPro, the company-wide cancellation add-on, runs $299 per month or $2,999 per year billed annually. Read the terms before you budget for it: it lets you cancel or modify eligible hotel bookings until noon on check-in day, overriding the hotel’s own policy, but the value comes back as a one-year travel credit rather than cash, coverage is not universal so eligibility has to be checked booking by booking, and nights already used are not covered.
The rewards ladder is a large-company feature. The Engine X card is a no-annual-fee business charge card issued by Fifth Third Bank N.A., with spending limits configurable by employee, category, or transaction. Rewards scale with annual spend on hotels and rental cars: 6% back from $0 to $250k, 7% at $250k, 8% at $2.5M, and 10% at $5M and above. Everyday non-travel purchases earn 1.5% at every rung, and flights are not shown earning above 1.5%. The headline number needs $5M in annual travel spend to reach, so a mid-market company modeling its return should be working from the bottom rung, not the top one.
The booking still lands on somebody’s desk. This one has nothing to do with pricing, and at executive level it tends to matter most. Engine is a booking platform, so its value arrives through an interface: an administrator sets the policies and budgets, and the traveler works inside them to put the trip together. If the trip is the same conference in the same city for the fourth year running, that is exactly the part the executive was hoping to hand to someone else.

1. Catch: Best Overall Alternative
Catch is the one option here that is not a booking platform. It is an AI Executive Assistant handling end-to-end admin work for executives, and business travel sits inside that work rather than beside it. No travel dashboard, no search screen, no results page, because nobody searches. The executive mentions the trip in Slack, by text message, over email, or on a phone call, and it gets booked.
More often, they do not mention it first. Catch reads calendar and email context and picks up the trigger on its own: a conference ticket that arrived in the inbox, a face-to-face meeting scheduled in another city, an airline ticket sitting there with no hotel booked against it. It proposes the flight and the hotel, and it picks the hotel by where the meeting actually is, within a ten-minute walk of the address rather than somewhere in the right metro area.
Policy gets respected without becoming a system the traveler has to operate. Where a company travel policy exists, Catch books within it, covering rates, approval flows, and authorized upgrades. What Catch does not do is sell a policy-and-spend console to a finance department. The person it is built for is the executive who travels, not the team that reports on travel afterwards. Personal preferences work the same way, covering airline, seat, flight times, hotel chains, and room type, and they get sharper over time because Catch collects feedback after stays and builds a profile instead of waiting for someone to configure a settings page.
Then there is everything after the confirmation email. Catch keeps scanning for better rates and will cancel and rebook when it finds one. It handles the last mile, real outbound phone calls included: ringing the front desk to confirm the room has what the executive needs, arranging early check-in or late checkout, booking a meeting room, reserving a restaurant, and finding past contacts at the destination to set up a catch-up while they are in town.
The cost comparison is worth stating plainly, because it is a different comparison from the rest of this page. A US-based executive assistant runs $120,000 to $180,000 a year all-in. Catch is a flat $99 a month with a 10-day free trial, and voice calls are included rather than metered. That is not an argument for letting anyone go. It means the repetitive admin gets handled and the person doing it today can move to the operational and in-person work that still needs a human.
Why business travel and not travel generally. Work trips repeat. The same executive, the same conference, the same route, fixed dates, a known objective, a known policy. Repetition and a clear objective are the conditions an agent performs well in, which is why Catch is built and positioned around business travel rather than leisure planning, where the open variables make a conversation a weaker place to start.
Expense reports, receipt capture, and reimbursement are not part of Catch today, so a company that needs those keeps its expense tool running alongside.
Security. SOC 2 Type II certified, audited by EY. Google Verified at CASA Tier 2. Data hosted in the US. Setup takes under three minutes and is fully self-serve.
Best for: executives and founders at US mid-market companies who travel the same routes repeatedly and want the trip, plus the admin around it, handled without operating a tool.
2. Navan: Best for One System Covering Travel, Expense, and Cards
If the reason for leaving Engine is that travel and finance live in different places, Navan is the closest thing to a complete swap. It puts business travel booking, expense management, and corporate cards in a single platform. The inventory covers flights, hotels, trains, rental cars, and black cars with negotiated rates, so ground transport does not need a separate arrangement.
Navan’s AI assistant, Ava, is a substantial part of the product. It uses a multimodal approach to learn traveler preferences such as amenities, room size, and loyalty programs, then curates compliant hotel options from them. Navan’s Waiver Agent monitors airline waivers in real time and alerts travelers to rebook before a disruption strands them. Finance managers meet a different side of Ava, one that summarizes spend by category, compares spend against policy, and projects future travel habits.
On the finance side there is receipt scanning with automatic transaction categorization, Navan’s own corporate cards with up to 1.5% back, and Navan Connect for linking existing Visa, Mastercard, or American Express corporate cards for automatic reconciliation. It supports 30-plus HRIS integrations. Travelers tend to like Navan Rewards, which gives them personal travel credit for booking under budget.
Pricing. Travel booking on the Business tier carries no booking fee; Navan states it is funded by travel providers’ commission fees. Navan Expense is free for the first five monthly expensing users, then $15 per user per month. The Business tier covers companies up to 300 employees; larger organizations are pointed to Enterprise, which adds dedicated support and corporate negotiated rates at custom pricing that is not published.
Worth knowing. Free travel and paid expense are two separate lines on the same invoice. If the reason for leaving Engine is the cost of the extras, price Navan on the expense side before assuming the swap is cheaper, because that is where Navan’s published fee actually sits.
Best for: finance teams that want booking, expense, and cards governed in one place. If the goal is putting travel and spend under a single system of record, that is the swap Navan is built for. Catch is aimed at a different job: handling the trip and the admin around it rather than giving you one more platform to run it in.
3. Perk (formerly TravelPerk): Best for Self-Serve Booking With Approvals Built In
Perk rebranded from TravelPerk in November 2025 as it widened from corporate travel into travel and spend. For a US buyer, the accurate description is travel booking with third-party expense integrations: Perk’s North American expense page describes integrating closely with the top expense tools in North America rather than selling its own spend product there.
The approval loop is the part it does well. Trip approval requests go out automatically through Slack, where an approver can read the trip summary and approve or decline inside the chat window, and the same flow works in Microsoft Teams. Travelers get offline mobile access to itineraries, booking details, and train tickets, which matters on the road far more than it does in a feature list. FlexiTravel is the standout: an opt-in program charging a 10% fee per trip that guarantees an 80% refund on cancellations made up to two hours before departure. Set against FlexPro’s one-year travel credit, that is a meaningfully different remedy for a similar problem.
Pricing. Travel Only plans pair a platform fee charged per company per month with a percentage of every booking: $0 per month plus 5% per booking on Starter, $99 per month plus 3% on Premium, and $299 per month plus 3% on Pro. The Perk Visa Debit Card carries cash back that depends on the tier, 0.5% on Premium and 1% on Pro. A team moving off Engine’s free platform should model booking volume against that percentage before comparing the monthly numbers, because the monthly number is not the whole cost.
Worth knowing. The per-booking percentage applies on every tier, so the platform fee is only ever half the bill. For a team currently stacking personal loyalty numbers with Engine’s rewards, confirm with Perk how loyalty numbers are handled on its bookings before you commit.
Best for: companies that want employees booking their own trips, with approvals landing in the tools the team already uses.
4. SAP Concur: Best for Heavy Policy and Approval Governance
Concur sits at the enterprise end of the market, and it answers one question well: what happens when the approval chains are genuinely complicated. It unifies travel booking, expense reporting, and invoice processing, and its strength is catching policy violations at the moment somebody tries to commit one. Travel policy is applied during booking, with out-of-policy options flagged in real time before a report ever gets submitted. Users can search, compare, and book flights, hotels, rail, and rental cars from one place.
The governance depth is real. Concur supports granular spending policy configuration by category, amount, geography, or employee group, and configurable approval hierarchies that route reports based on spend thresholds and organizational structure. Expense automation covers receipt capture, auditing, and compliance, and the invoice product handles accounts payable including purchase order matching and approval routing. ExpenseIt reads receipt photos with OCR on mobile and creates categorized entries on its own. Joule, Concur’s AI copilot, uses natural language to automate tasks, answer policy questions, and move around the system, and Concur Travel includes a Booking Agent that helps search and book compliant travel within preferences and budgets.
Pricing and a structural catch. Concur publishes three tiers, all with unlimited users: Base at around $7 per expense report, Plus at around $11 per expense report, and Premium at custom pricing. Base includes Concur Expense alone. Plus adds ExpenseIt, the User Support Desk, and reporting, and is still expense only. Concur Travel appears only in the Premium tier. If you are leaving Engine because you want travel booking, the entry tiers do not provide it. No tier comes with a free trial.
One more thing on the numbers. Concur charges per expense report with unlimited seats while Navan charges per expensing user per month. Those are different pricing shapes and the raw figures do not belong next to each other. Compare the model against how your company actually behaves.
Best for: large organizations with multi-layered approval chains and audit obligations a lighter tool cannot satisfy.
5. Ramp: Best for Travel Attached to a Spend Platform
Ramp comes at the problem from the finance side. It is a spend management platform built around corporate cards, expenses, accounts payable, and accounting, with travel booking added to the stack rather than sitting at the center of it. That framing matters: most of what Ramp does is not travel, so it is less a like-for-like swap for Engine than a way to stop treating travel as its own category.
On travel itself, users can book flights, hotels, and car rentals. Booking for an external guest is handled cleanly: the guest receives their details by email without needing a Ramp account, though guest booking covers flights and hotels rather than rental cars. Ramp also lets people book with any travel provider and then matches those transactions to bookings and captures the receipts, so a trip booked outside the platform still lands in the same place. Phone support for travel, available 24/7, is gated behind the paid tiers.
Pricing. The Free plan is $0 per month per user and includes unlimited physical and virtual cards. Plus is $15 per month per user plus a platform fee based on team size, unlocking things like AI-driven expense reviews and the ability to lock a card automatically when a required receipt has not been submitted. Annual billing takes 20% off Plus. Enterprise is custom priced with a dedicated account manager and priority 24/7 global support. Expenses and receipts can be completed over SMS or Slack, invoice data is extracted with OCR, and there are direct integrations with QuickBooks Online and Xero.
Best for: finance teams that want card, expense, and travel data in one place and are comfortable with travel being one module of a larger spend platform.
What Leaving a Free Platform Actually Costs
The comparison most teams run is the wrong one. Engine’s $0 goes up against a competitor’s monthly fee, the free option wins, and the decision closes there.
The number missing from that calculation is time. Engine, Navan, Perk, Concur and Ramp are all platforms a company adopts and runs its travel through. Planning a trip, changing it, and rebooking it when the meeting moves all happen inside them. That labor never shows up on an invoice, which is precisely why it never gets compared. For a senior executive, an hour spent inside a booking interface is the most expensive hour in the whole travel budget, and it is the one line nobody prices.
There is a second cost that a free booking platform was never meant to cover: everything around the trip that is not a booking. The calendar has to reshape around travel days. Meetings at the destination need scheduling across time zones. The inbox keeps filling while the executive is in the air. Somebody has to call the hotel about the late checkout and move the meetings when the return flight slips. An assistant already running the calendar and the inbox treats the trip as one more piece of context it is already holding.
Match the Alternative to Who Actually Travels
The right choice depends less on features than on who in the company is getting on planes.
If it is crews and field teams, Engine’s shape is hard to beat and leaving may be the wrong move. Group bookings of nine or more rooms, extended stays, incidental holds covered upfront, and one consolidated invoice are all built for exactly that. The free platform is a genuine advantage when the travelers are numerous and the trips are standardized.
If it is a broad employee base with real compliance obligations, you want a platform with a finance owner. Navan for a modern combined travel-and-expense build, Concur when the approval chains are genuinely complex, Ramp when travel is one module of a wider spend problem, Perk when self-serve booking with fast approvals is the priority.
If it is a handful of executives traveling constantly, the question stops being which platform to buy. Every option above is software somebody has to work in, and when the traveler is an executive, that somebody is usually an assistant. Handing the tool over relocates the work; it does not remove it. That is the scenario Catch was built for, and it is the most common reason these searches start.
Our Top Pick
For executives at US mid-market companies, Catch is the strongest alternative on this list. Engine, Navan, Perk, Concur, and Ramp all do what they were designed to do, and two narrow cases favor one of them outright: if you move large crews and want free, centralized hotel procurement, stay on Engine, and if your requirement is a finance-owned spend console with granular reporting, Navan or Concur will serve that better than Catch does today.
Those are specific requirements, and they belong to the operations and finance functions rather than to the traveler. For everyone else, the real question is what the executive’s day looks like. Catch takes the booking out of it entirely, works from context they never have to supply, stays with the trip afterwards to catch better rates and handle the calls that need making, and carries the surrounding admin while it is at it. One flat number, $99 a month, that does not move with how much the team travels. No percentage per booking, no per-report charge, no per-user tier, no add-on to buy before the cancellation cover works.
Frequently Asked Questions
What is the best Hotel Engine alternative in 2026?
Catch, for executives who want business travel handled rather than searched for. It books flights and hotels from calendar and email context, then keeps managing the trip; ground transport stays with the traveler. If you need a platform-shaped alternative with expense management attached, Navan is the closest like-for-like swap.
Is Hotel Engine free?
The booking platform is. Engine’s pricing page states it is free rather than a free trial, with no membership fees, no contracts, and no minimum spend. Engine separately sells paid extras, including the FlexPro cancellation add-on and the Engine X card, so the accurate line is that the booking platform is free, not that everything at Engine is free.
Why is Hotel Engine now called Engine?
Hotel Engine rebranded to Engine when it expanded beyond lodging. The platform now books flights and rental cars alongside hotels. Search demand still sits on the old name, so Hotel Engine and Engine refer to the same company.
How much does FlexPro cost, and what does it actually cover?
FlexPro is $299 per month or $2,999 per year billed annually, and it covers the whole company. It lets you cancel or modify eligible hotel bookings until noon on check-in day, overriding the hotel’s own policy. Two details to settle first: the value returns as a one-year travel credit rather than cash, and coverage is not universal, so eligibility has to be checked per booking. Nights already used are not covered.
How does the Engine X card rewards ladder work?
The Engine X card is a no-annual-fee business charge card issued by Fifth Third Bank N.A. Rewards on hotels and rental cars scale with annual spend: 6% back from $0 to $250k, 7% at $250k, 8% at $2.5M, and 10% at $5M and above. Everyday non-travel purchases earn 1.5% at every rung, and flights are not shown earning above 1.5%. Reaching 10% requires $5M in annual spend, so most mid-market companies should model the lower rungs.
What should I check before moving off Engine?
Price the things Engine does that your replacement may not. Group room blocks of nine or more and extended stays route to a dedicated Groups team. Incidentals coverage can put hotel incidental holds on the corporate invoice instead of a traveler’s personal card. Direct Bill consolidates travel charges onto one invoice. And travelers can attach their own hotel loyalty numbers to earn alongside Engine Rewards. If any of those are load-bearing for your team, confirm the replacement handles them before you switch.
Does Concur include travel booking?
Only on its top tier. Base includes Concur Expense alone, and Plus adds ExpenseIt, the User Support Desk, and reporting while remaining expense only. Concur Travel appears in the Premium tier, which is custom priced, and no tier comes with a free trial.
Can an AI assistant actually book business travel?
Yes. Catch has been booking business travel since July 2026, operating as the travel agent itself with its own booking infrastructure, covering flights and hotels and then continuing to manage the trip. Ground transport is not part of it. Business travel suits an agent because it repeats and has a fixed objective, which is why Catch is built around work trips rather than leisure planning.
Does Catch follow a company travel policy?
Yes. Where a travel policy exists, Catch books within it, respecting rates, approval flows, and authorized upgrades. What Catch does not do is sell a policy-and-spend-control console for a finance team to operate. The policy is honored on the traveler’s behalf rather than presented to them as a compliance system to work through.
Which is better for a mid-market company, Engine or Catch?
Catch, for companies where a small number of executives travel frequently and the real cost is their time. Engine is the better pick in one narrow case: high-volume, standardized hotel booking for field or project crews, where free centralized procurement and group bookings are the whole requirement. If the goal is to stop operating a booking tool, Catch books the trip, handles the last-mile calls, and covers the admin around it for a flat $99 a month.
