Even in that range. I've flown business class--generally because a client was paying or an upgrade through a combination of miles and 3 digit $s--whenever I'm tempted I come down to thousands of dollars will pay for a lot of meal upgrades and theater on the other side of the pond. It's a lot of money, even for someone who can afford it, to save a few hours or be more comfortable for a day in a metal tube in any case. If it's just pocket change, why not? But maybe now you just fly Netjets.
