Expedia App: Book Flights, Hotels, and Vacation Packages and Manage Your Trips

Expedia is one of the largest online travel agencies in the United States. It lets you search for and book flights, hotels, rental cars, cruises, and vacation packages all from a single website or app. One of its biggest advantages is the ability to bundle a flight and hotel together in a "package deal," which can save you money compared to booking each piece separately.

When you book through Expedia, you earn One Key points (called OneKeyCash) on each purchase. These points can be applied as a discount on future bookings, essentially giving you a small reward every time you travel. If you already use Hotels.com or Vrbo, those bookings also count toward the same One Key rewards program.

Expedia's "All-Inclusive Resorts" filter is particularly popular with vacationers who want to simplify their trip planning — one price covers your room, meals, and most activities. The filter makes it easy to compare all-inclusive options at your destination.

The Expedia app keeps all your upcoming trips in one place. You can see your flight details, hotel check-in times, and car rental pickup information without digging through your email. The app also sends push notifications about gate changes or delays so you stay informed on travel days.

For domestic travel, Expedia is a strong option because it has negotiated rates with many hotel chains that are competitive with or better than booking directly. For international travel, it is always worth comparing Expedia's price against the hotel's own website, since some international properties offer lower direct rates.
