Wow - how can a team of developers build a flight travel app and NOT include a "one-way" option? Are they naive enough to think that travelers have only one flight method need (round trip)? I will update my review IF and WHEN the devs bring that option to the app.
*UPDATE (May 9, 2016)
I just redownloaded this app to give it a try... I just finished my first flight search and the app provided ZERO results, only an error. After checking what the error was through the apps built in utility, the error explanation I received was that my error was due to "partially degraded service. Oh man... This app stinks!!
