I'm planning to fly from LHR to SFO in late September and I'm not sure if I should go with UA or BA. Prices are similar and both airlines fly 747 on that route.
Which is better? I flew in BA's 747 about 5 years ago (to IAD) and wasn't impressed by the quality. It had really dated feel. My girlfriend's seat was moving in funny way (the bit you are sitting on) and it wasn't too clean.
How about UA jumbos? Are they good?
