There is no part of this app that reliably works. ... App stopped working just before my flight departed, wouldn't display my boarding pass. Why that isn't cached, I have no idea. And of course they will *sell you* a paper boarding pass. ... Edit: also when trying to book, it "times out for 15 minutes of inactivity" after 30 seconds ... Edit 2: also when you email the app support email address that they post as replies to negative reviews, outlook gives a "message undeliverable" error.
