Not everyone chooses Expedia when booking a vacation package, especially points-savvy travelers, but this discount might swing your decision.

Here are the details of this promotion and whether it's a good deal.

Expedia One Key Promotion: Save Up to 40% off Select Hotels and Vacation Packages

If you're not familiar with One Key Rewards, it's the loyalty program for Expedia, Vrbo, and Hotels.com, where members earn bonus points on stays and packages. Although One Key isn't nearly as good as the old loyalty program, we're starting to see promotions that offer considerable savings on top of bonus points.

While One Key Rewards is new, Expedia turns 30 this year. To celebrate the milestone, One Key Rewards members can save up to 30% on select hotels and vacation packages. To take advantage of these savings, book your stay or package by October 7, 2026. Eligible travel dates are through March 31, 2027.

The following offers are available during this promotion:

  • Up to 30% off select hotels and vacation rentals for One Key members
  • 25% off select vacation packages
  • Deals on select car rentals and flights
  • 15% or more off select activities for One Key members
  • 10% off select cruises for One Key members
  • Limited-time OneKeyCash opportunities
  • Flash deals of up to 40% off select hotels from September 9 through September 11, for stays through November 4, 2026
  • A stay coupon beginning September 15 (more details coming soon)

This promotion does not require registration. Some offers are available to all travelers, but One Key members get the best opportunities and earn OneKeyCash with bookings. If you are not already a member of One Key Rewards, you can join for free. You can find the savings on the Expedia website or in the Expedia app.

Once you've created your new loyalty program account, make sure to link it to your AwardWallet account. Don't have an AwardWallet account yet? Sign up for free and track unlimited rewards programs and travel plans.

After you join or sign in, you will automatically see the discount applied to your options. You will see that some offers are nowhere near 30% off, while others are even higher. Three nights at the Days Inn & Suites in Phoenix is only 15% off, while three nights at the Wekopa Casino Resort is 42% off.

Our Take

Booking a hotel or vacation package with this One Key promotion to save up to 40% is a good opportunity. Of course, you might get better rewards or savings by booking directly through your favorite hotel loyalty program. On the other hand, Expedia is a convenient way to search for and book hotel options simultaneously with your flight, car rentals, excursions, and more.

One Key Rewards members should definitely consider this promotion, especially the flash sale through September 11, but keep the eligible stay dates in mind. Savings are also available for flights, car rentals, activities, and cruises, not just hotel stays and vacation packages.
