No, I flew international first class and international economy. I stand by what I said, it's the difference between being uncomfortable and being slightly less uncomfortable. You're still stuck on a plane.
Which airline, out of interest? I understand that American airlines have less attractive Biz/First offerings than European and Middle-Eastern airlines.
Doesnt matter though, no matter what they do they aren't going to take away the fact I'm stuck on a airplane for 15 hours. I'm also the kind of person who prefers to get up and get something rather than be served.
