Well, that's my concern is that UA might not be might fine. My last UA c-class flights DEN>LHR abd AMS>ORD>DEN had problems with the seats. 2 footrests wouldn't stay up. One monitor would flop over. One seat had no audio. Food was sketchy. (Anyone had the Charlie Trotter bacon wrapped beef? Couldn't even cut through it.) And that's on the 777. I'm imagining things are worse on the 747's aren't they? At least SQ has large screens at each seat even in coach.
