Book Southwest Flights on Expedia Platforms
Expedia Group and Southwest Airlines have announced a new partnership. That means that you can use Expedia platforms to book Southwest flights that cover 117 destinations in 11 countries, including the U.S., Mexico, and the Caribbean.
Starting this week, travelers can begin booking select Southwest flights on Expedia, with the ability to book any Southwest flights by Thursday. Customers can book on Expedia and other Expedia Group brands including Travelocity, Hotwire, Orbitz, and CheapTickets.
This is a big change for the airline, which has always required customers to book directly through its channels. The company did allow its fares to show up on Google Flights searches last year, but you still have to click through and book directly with Southwest.
