Southwest Airlines has released an update to its iOS® mobile app available now in Apple®'s App Store for iPhone®. The release includes an all-new app with a faster and more streamlined interface, providing an enhanced mobile experience for Customers on iPhone.

"New features such as express check out make booking Southwest's low fares even easier for our most frequent Customers," said LeighAnn Davis, Southwest Airlines Senior Director of Digital Marketing.

"The app's new look and feel adds to the redesigned user experience and helps make everything from browsing flights, to checking in, to day of travel easier."

In addition to browsing and booking flights, Customers also may book rental cars, access upcoming trip information, and save boarding passes to Apple Wallet from within the app.

Integration with a user's Rapid Rewards® account allows Members to use the new express check-out feature as well as access a fresh interface for tracking progress toward Rapid Rewards A-List, A-List Preferred, and Companion Pass tier status.
