I have the MP Club Card and the FA has shown me that my assigned seat is on the app. Nothing has showed up in the last 2 months, it's never shown up. It's nickel and dime crap like this I strive to avoid taking on myself when traveling, especially exorbitantly priced sandwiches. Since my company requires itemized receipts with everything, even a .10 purchase, that's probably $50 I'll never see again.
Thanks United. Just give me the dang paper receipt and stop finding solutions until you fix what you got.
