Totally agree. The one thing UA has done better than a lot of airlines is mobile app capabilities. And I don't give props to UA often. Very user friendly app when it comes to anything you might need to do day-of or within a few days of traveling. Things such as changing flights, seats, upgrade list, track aircraft routes/status, etc. are all much easier on UA. They used to list the baggage claim which was nice, but that got taken off. One nice addition would be baggage tracking.
