Got an email today telling me I could win a million points if I checked in via the phone app. Downloaded the app, signed in and was told that they could not retrieve my reservations due to various reasons (techno gibberish). Decided to look at the rest of the app and promptly got send back to the actual web site on my phone's browser. At that point, decided that the app wasn't worth taking up space on my phone. Let me know when it's all grown up and ready to use - great first impression, btw.
