Have a weird one I am trying to figure out. Flight UA3666 today CVG->EWR
App shows upgrade list as "Full" with all 6 checked in. But seat map shows 5 unassigned seats in First. Can't think of how this is possible other then an error of some type.
I checked the website. Shows same seat map, but only 1 checked in. I guess that is possible, though unlikely that 5 passengers in First haven't selected a seat.
