Mostly I was thinking lounge access and the free checked bags. I haven't flown UA since last year and didn't realize they had re-done the boarding process again. Now I'm mostly trying to figure out if I even want to try to requalify for 2P or just credit all my miles to TK. I don't expect to be doing too much travel on UA and 2P doesn't really seem worth it, but that's another story altogether.
