Barbara - do they actually get to use them for personal travel?
Well my friend certainly did. She has worked for a number of big companies over the years, top 4 accountants, plus others, and used to travel at lot with work. She and her DH (50s, no DC) have had a US holiday every 2-3 yrs and they have never ever gone economy, they have always bought at least 1 ticket with her air miles, sometimes both. So, yes, in her case, they have used them for personal travel! They are quite frugal, despite her earning very well, so would not have bought business/1st tickets without the air miles.
An interesting thread, as a friend once said, why worry about other peoples money, its not yours and never will be! But human nature makes us be interested I suppose.
Like Lazy - my late teens kids have survived without going to Florida, and with only a couple of trips to Eurodisney, one tagged onto a french holiday. We are going US this year, but neither wanted to go Florida, so we going W coast instead.
Its only the second long haul holiday we have done, we have preferred flexibility of caravan hols when DC younger, despite having a decent amount of disposable income (due to being old enough to have bought houses straight from uni!).
I however feel slightly embarrassed talking about the holiday, not sure why, I suppose it feels like bragging and I almost feel embarrased about being very comfortable financially. Most poeple know that my mum died last year, so could extrapolate that I probably had an inheritance, but even so, my nature is keep a low profile on the money front!!
