For a long time now, Southwest Airlines' Android app has been awful. I mean just lamentably bad. No, seriously, here are some screenshots of the app before today's update... and oddly, Southwest hasn't even updated the screenshots in the Play Store.
See? It's like someone got the only app developer from TWA to work on it. The app has been given a complete overhaul with today's update, bringing both the interface and the capability up to snuff.
