Ok, sorry to revive a 2 year old thread, but I didn't wanna start a new one and get ripped for it!

Is this STILL not possible? With all the updates this app has gone through? I was at the movies the other day when my upgrade alarm went off, couldn't do it! I was very surprised. I knew I had seen the "use eUpgrade" check box before, but it was when I was checking in. I tried in safari as well but I couldn't get it to work. I can't think of any reason why they wouldn't be able to do this, but then it can't just be laziness either. The people using the upgrades MOST would be the ones on the road the most as well, many of them would be using iPads/iPhones while at hotels or on the road I'm amazed this hasn't been a priority or a real sticking point for people.

Or is this just a case of me not being able to find a setting somewhere?
