What we like
- Hotels, flights, cars, activities and packages in one account.
- Free One Key rewards: $1 of OneKeyCash is $1 off eligible travel, with no blackout dates.
- Gold and Platinum members get Price Drop Protection on eligible flights booked in the app.
- OneKeyCash is shared with Hotels.com and Vrbo.
What to watch out for
- OneKeyCash has no cash value and can’t be transferred.
- You must be signed in when you book to earn rewards.
- Changes and refunds follow each hotel’s or airline’s rules.
The fine print
- OneKeyCash is not earned on taxes, fees, deposits, insurance or cancellation charges.
- OneKeyCash stays pending until your trip is completed.
- Prices are in USD on the U.S. site.
- Legitimacy signals we found: part of Expedia Group, published One Key terms, and 24/7 support.
Who it’s best for
Travelers who want hotels, flights and cars in one booking site.
- Travelers who want to book hotels, flights, cars and activities in one place.
- People who want rewards they can use across Expedia, Hotels.com and Vrbo.
Who should skip it
- Not for anyone who wants to deal directly with the hotel or airline for changes.
