I'm planning a trip to LAX next winter just as I did this year and I'm looking forward to again flying on the mighty 747-400.

However, this time I'd prefer to fly on the upper deck. Yes, I know some say they prefer it down in the front of the lower deck as it's supposedly very quiet, but this time I'd love to go up there.

Anyway, I plan on flying either LH from FRA or BA from LHR - what are my options to fly on the upper deck? No, I don't have any preferred status on either airline. Could this be done at all without having some sort of a preferred customer status?

Thanks!
