Have flow BA 747 to Heathrow twice enroute to other cities in Europe. We were truly excited to ride on the Jumbo Jet. In the end I guess you get what you pay for. Economy is sort of like booking an inside cabin on the lowest deck on a cruise ship. The service was adequate, but the food was poor, the airplane was in rough shape and worst of all the seats are very close together. I am 6'0 and felt like I was shoved in the trunk of a subcompact car. When we got to Heathrow (Old English for Hell) I was wrecked because I was unable to sleep because I could not get comfortable.
