Ah, one of the bucket list items standing from my youth when the UD was a lounge for F pax and, oh, so glamourous, my first F on a BA 747 some 35+ years later was just a wonderful experience! The only thing missing was being on the UD. But I'd had the good fortune to have done CW upstairs several times by the time I got to F so I didn't really miss much! I've also not been upstairs since thinking I'd try F.....it's habit forming and now I'm looking for a group or some program to help me stop the bleeding from my bank account!
