Works pretty good if you have an American passport, but the app is very buggy when you have to enter in a passport from another country, or a Permanent Residents Card. It asks for the card, but then tells you to take a photo of the passport. On one screen, you take the photo but then can't submit it because there is no button. I tried numerous times to check in my wife's passport and at one point it looked like it was processing; then it threw an error message.

Absolutely worthless. Flight was delayed 8 hours, yet throughout the 8 hours I was getting constant push notifications to go board it now. Then the flight got cancelled and some 10 hours later I'm still getting notified that boarding has started. While this was going on all I wanted to do was get some help with rescheduling the flight and hotel and the app was completely worthless. it doesn't even have an opinion to talk to an agent when things go wrong. Worthless.

Everything's fine until anything gets weird. Delays or cancellations? Good luck making changes. We drove to the airport and spoke with a supervisor long before anyone responded via phone or app. Allow people to actually change their flights in the app. Update app info to show your diverted flight and what options I have for my follow-on flight. Don't charge customers hundreds per seat to rebook, even though you claim I'm eligible for free rebooking. Have functional toilets on your aircraft.
