Whether you’re thinking of renting a beach home or planning a multifaceted trip requiring a flight, hotel stay and car rental, you now have an opportunity to earn rewards, receive discounts and reach elite status through a new loyalty program.

Expedia Group brands including online travel agencies Hotels.com, Expedia and vacation rental site Vrbo are joining forces for a program called One Key.

One Key has replaced the existing travel rewards programs used by Hotels.com and Expedia. The inclusion of Vrbo makes it the first loyalty program among major vacation rental sites as well.

Note that there are some limitations around booking through an online travel agency, and previous Hotels.com Rewards loyalists may find earning a free night is more difficult under the new program.

However, for some travelers, One Key will provide an avenue to earn rewards for almost every element of their trip, from flights to hotels to vacation rentals to experiences.

Here are some things to know about the One Key program.

How the One Key loyalty program works

The One Key program combines the booking possibilities from three sites into a lot of earning potential. It’s probably most beneficial for the more infrequent travelers who may not stay or fly enough with one brand to earn perks but could use rewards on all of their travel spending combined.

In other words, it doesn’t matter which of the three sites you’re using. Loyalty currency you earn and elite status progress you make will all count toward a single program.

Like with most loyalty programs, One Key is free to join.

How to earn rewards on Vrbo, Hotels.com and Expedia

The One Key program will use a new loyalty currency: OneKeyCash. Members will be able to earn through:

Eligible stays on Hotels.com.

Eligible rentals on Vrbo.

Eligible flights, hotels, rental cars or activities on Expedia.

Members will receive 2% in OneKeyCash for every dollar spent on eligible hotels, vacation rentals, activities, packages, car rentals and cruises and 0.2% in OneKeyCash for every dollar spent on eligible flights. That means if you spent $100 for a hotel night, you’d earn $2 worth of OneKeyCash.
