I'm with
PAXboy - I'm delighted to travel in F or C when someone else is paying, but otherwise it's the cheapest ticket at the back. Unless you really can't cope with a standard seat (if you're extra tall, extra wide
), I can think of much better ways of spending a couple of hundred pounds than renting a big seat for a few hours. Perhaps the only other justification is "I've got so much money that I'll never be able to spend it all", but the folks I've met who are in that fortunate position tend to be even meaner than I am!
I was once on holiday with a tour group that included a nice guy in his 80s who was minted - home in Jersey, second house in Gstaad, etc. The courier suggested to him that he upgrade to Club on his flight back for an extra £1500 - he was outraged at the idea of wasting all that money, despite the fact that he could have spent the rest of his life flying in First without making a dent in the interest on his interest.
