Don't pay for premium economy! What a ripoff! Premium economy seats on this 747-400 are as uncomfortable and the same size as regular economy. There is no additional legroom. And the food is almost inedible. Well, it is inedible. My advice -- take a different airline to and from London. Fly to Dallas, New York, L.A., and fly premium economy from there. Or just fly economy on BA, knowing that this is a nonstop flight with no competition and no desire to be any better than a 2nd class airline.
