Well, as it has been more than 25 years since I've been on an international flight, I've got a few things to learn.
I don't think there was such a thing as economy vs. premium economy back in 1987. I think it was just "regular" and "first class/business."
Are these all new planes that have been built in the 21st century?
Can anyone tell me if it's worth paying more for premium on a flight to Europe from the US? Of course I am trying to keep costs as low as possible. But I don't want to feel awful for 6+ hours.
(I have been on domestic flights in the 21st century. I think I just flew economy. Are international flights much different?)
