I meant to say that whenever possible, United/Continental has a much better track record of accomodating minyunim then El Al does,going so far as to vacate the galley for 30 minutes for a minyan, yes, I was once in such a situation , where a respectful request was made, and the crew granted this privilige.
However You are 100% correct, that if this inconveniences the crew or fellow passengers, then you should rather daven in your seat
