There is a very special run for 600 tp from mco-mia-lax-(sfo|las) and back in yup class and alike which you might want to try. it does not take away the need for you to have that four flights.
Remember that you can take a short trip from London to somewhere in Europe, even a day trip or two and that will result in flights too like a short hop to Amsterdam or so.

Thanks for the tips, but my goal isn't to travel for the sake of it, so much as to be treated humanely when I do have to travel.
