Expedia vs Hotels.com Flights: Which One Wins in 2026?
Some links on this page earn us a small commission, at no extra cost to you. Full disclosure.
Expedia and Hotels.com are owned by the same parent company (Expedia Group), so most people assume they are interchangeable. They are not. The flight inventory is similar but the loyalty programs, package deals and pricing on individual bookings can differ in meaningful ways. This is the honest comparison of Expedia vs Hotels.com for flights.
The Short Answer
Expedia wins for booking flights with hotels in a single package, has the stronger overall rewards program (One Key), and is the better choice for travelers who use Vrbo for some accommodations. Hotels.com Flights is a thinner experience oriented toward Hotels.com loyalty members who want to keep their rewards in one place.
For most nomads, Expedia is the right pick if you only choose one. Hotels.com is the right pick if you already book most of your hotels there.
Key takeaways
- Expedia wins for flight plus hotel packages and has the stronger One Key rewards.
- Hotels.com Flights makes sense if you already book most of your hotels on Hotels.com.
If your flight is delayed or cancelled
The Shared DNA
Both platforms run on the same Expedia Group backend. The flight inventory, the pricing engine, and the customer service systems are mostly shared. So the same flight from Lisbon to Bangkok shows up on both with the same base price most of the time.
The differences come down to:
- Loyalty program design
- Package deal mechanics
- UI and search experience
- Brand specific promotions
Expedia: The Broader Platform
Expedia is the flagship brand. Flights, hotels, vacation rentals (through their Vrbo brand), cars, cruises, packages, all in one platform. The flight booking is integrated into the broader vacation planning flow.
Where Expedia wins:
- One Key loyalty program covers hotels, Vrbo and packages with shared points (Expedia says flights do not earn OneKeyCash)
- Package deals (flight plus hotel) often save money compared to booking separately
- The Add to Trip feature lets you build out a multi component trip and book it all at once
- Wider inventory of vacation rentals via Vrbo integration
- Trip protection (cancel for any reason) available on most bookings
What to watch for. Some package deals lock you into specific hotels with limited cancellation. Always read the cancellation policy on the package vs the components.
Hotels.com Flights: The Side Feature
Hotels.com is primarily a hotel platform. Flight booking is a secondary feature added so loyal Hotels.com Rewards members can book everything in one place. The flight inventory is the same as Expedia, but the UI is more hotel centric.
Where Hotels.com Flights wins:
- Since 2023, Hotels.com bookings earn One Key rewards, shared with Expedia and Vrbo
- Cleaner UI for travelers focused on hotel first
What to watch for. The flight booking is functional but feels like an afterthought compared to Expedia or Skyscanner. No package deals as integrated as Expedia.
The One Key Loyalty Program
In 2023 Expedia merged the loyalty programs of Expedia, Hotels.com and Vrbo into One Key. The program works like this:
- Earn One Key Cash on eligible non-flight bookings across the three brands (Expedia says flights do not earn it)
- Redeem One Key Cash on future bookings on any of the three brands
- Status tiers (Blue, Silver, Gold, Platinum) unlock added benefits
- Reach higher tiers based on the number of nights and bookings per year
Higher tiers need more bookings per year and add extra perks. Check the current One Key terms for the exact thresholds and benefits, since Expedia adjusts them.
Expedia vs Hotels.com Flights: Side By Side
| Feature | Expedia | Hotels.com Flights |
|---|---|---|
| Flight inventory | Shared with Hotels.com | Shared with Expedia |
| Loyalty program | One Key | One Key (shared) |
| Loyalty currency | One Key Cash | One Key Cash (stamps replaced in 2023) |
| Package deals (flight plus hotel) | Strong, integrated | Limited |
| Vrbo vacation rentals | Integrated | Not integrated |
| UI focus | Full vacation planning | Hotels first |
| Best for | Trip planners, package buyers | Existing Hotels.com loyalists |
When To Use Expedia
Pick Expedia if:
- You want to book flights plus hotel in one transaction (package deal savings are real)
- You use Vrbo for any of your accommodations
- You are starting fresh and want to build One Key status
- You like vacation planning all in one place
When To Use Hotels.com Flights
Pick Hotels.com Flights if:
- You already book most of your hotels on Hotels.com
- You book hotels far more often than flights
- You prefer the simpler Hotels.com interface
- You only book occasional flights and want to keep your loyalty in one program
How They Stack Up Against The Other Engines
| Tool | Best For | Where It Wins |
|---|---|---|
| Expedia | Package deals plus flexible trip planning | Flight plus hotel savings |
| Hotels.com Flights | Hotel first loyalty travelers | Maintaining single loyalty program |
| Skyscanner | Flexible flight search | Everywhere search, broad inventory |
| Trip.com | Asia flights | Better intra Asia inventory |
For most flight searches Skyscanner is still the better starting point because it shows direct airline prices alongside OTA prices. Expedia and Hotels.com Flights win specifically when the loyalty program, the package deal, or the integrated hotel booking adds enough value to justify booking through the OTA.
The Hidden Cost Of OTA Bookings
Worth mentioning. When you book a flight through an OTA (any OTA, not just Expedia or Hotels.com), customer service if something goes wrong is with the OTA, not the airline. Disruption recovery, refunds and changes can take longer because the OTA is the intermediary.
For straightforward flights this is usually fine. For complex itineraries or routes through countries with frequent disruptions, booking directly with the airline can save you a headache when things go wrong.
One more thing to know if you fly to or from the United States: the US Department of Transportation's 24-hour rule (a free cancellation within 24 hours for a flight booked at least seven days before departure) is written for airlines. DOT's own FAQ says it does not apply to ticket agents such as online travel agencies, which may offer something similar by choice. If you booked through an agent, DOT advises contacting the agent first for a refund. Read the cancellation terms on the booking page before you pay.
The Affiliate Side
Expedia Group runs its own affiliate program, the Travel Creator Program, paid out through Partnerize. It advertises up to 4 percent commission on qualifying transactions through its Travel Shops feature (September 2026). Check the program for current rates per product.
Compensair is another claim service for the same situation: its site says it helps you claim compensation of up to 600 euros for a delayed or cancelled flight or overbooking.
Final Take
If you are picking between Expedia and Hotels.com Flights, Expedia is the better choice for most nomads. The package deal integration, the broader inventory across Vrbo, and the deeper vacation planning experience all add up.
Hotels.com Flights remains relevant for travelers who already book most of their hotels on Hotels.com and want one loyalty program for everything. If you start fresh today, build One Key status on Expedia.

FAQ
Are Expedia and Hotels.com the same company?
Yes, both are owned by Expedia Group. They share inventory, payment systems and the One Key loyalty program, but the brand experiences are different.
Is Expedia cheaper than booking directly with the airline?
Sometimes yes, sometimes no. For straightforward single airline trips the direct airline website is often cheaper. For multi component trips (flight plus hotel) Expedia packages often save real money.
What is the One Key loyalty program?
One Key is the combined loyalty program for Expedia, Hotels.com and Vrbo. You earn One Key Cash on eligible non-flight bookings across the three brands (flights do not earn it, per Expedia) and redeem on future bookings. Status tiers unlock added benefits.
Should I book flights on Expedia or Skyscanner?
Skyscanner is better for the initial search and price comparison. Expedia is better if you want to book flight plus hotel together or build a multi component trip in one transaction.
Does Hotels.com Flights affect my Hotels.com Rewards stamps?
Hotels.com Rewards stamps were replaced by One Key in 2023. Bookings now earn One Key Cash, which you can use across Expedia, Hotels.com and Vrbo.
Does the US 24-hour cancellation rule apply to flights booked on Expedia?
Not automatically. The US Department of Transportation rule covers airlines, and DOT says it does not apply to ticket agents such as online travel agencies, although agents may offer similar terms. Check the cancellation terms on the booking page before you pay.
