Trip names
This annoys me to no end - when I go on the AA app or on the AA website and look at my ticketed (or held) trips, it always 'names' the trip by my first connection, not my final destination. For example, if I'm flying LAX-DFW-ATL, it defaults the trip to 'LAX-DFW' not 'LAX-ATL'. I used to be able to change the name of an itinerary but the 'improved' website interface I can't find that option anymore. So, at a glance I have numerous trips 'LAX-DFW' even though I have zero intention of visiting Dallas outside of Terminal D over the coming months...
