[One exception, possibly no air vent in row 6 if CE goes that far back, equipment depending]. It's also a very short flight. So I'd leave it until OLCI. If you were a larger family group in Euro Traveller then I may suggest differently. Your baggage should be through checked, just have your BA locator and flight number handy for the Dulles sector.
