Im looking to go to NYC in Sept / Oct and i was pricing up flights- it will cost me £20 more to fly with united and get my flight back on Premium Economy then it would to fly with BA on Y (its coming up as £570 return). I have never seen BA LHR-NYC flights so expensive? I get covid and they need to make their money back but this is an off peak flight and im confused as to how its coming up as so much..

Is there a reason other than BA being overpriced?
