That may be a bit of a sweeping statement. A good lawyer might be on £300k. Good fund managers on much more. You can do an awful lot of flying on that...
OK, fair point... I exaggerated a little.
Also, "free" is not necessarily "single". If you are a bloke who likes flying, and you shack up with a woman who hates it, who is to blame for this??
Oh sure, I was alluding more to the arrival of children. I'm talking about people earning £50-60k, who suddenly find that the newly-arrived kids are soaking up most of their previously-disposable income... difficult to justify even about £3-4k a year in that situation. I suspect there may be quite a lot of ex-flyers in that situation. Who knows, maybe I'll be in that situation myself in a few years? Given my career as an electronic engineer, I'm unlikely to make lawyer-style money unless I strike entrepreneurial gold.
