If someone is willing to pay them that much, then I guess so.
As for myself, I'd happily pay an extra $4 for an airline ticket (assuming my other conditions for flying are met) to see 4 hot babes in tight skirts who smell nice, smile nice, and look nice.
Some things in life are worth the price, and I can't think of too many better bargains than paying $4 to flirt with and stare at 4 women at 30,000 feet.
I can tell you don't fly much lately.
First, most of the women have seen some track. I live across the street from an AA FA, 20 years in the business. She's got the body of a 20 year old, and the face of a 50 year old; her actual age is 38.
In addition, the flights I take on AA seem to always have male stews on them.
I've seen some talent on SW flights, but, even there you run across ladies in shorts who shouldn't wear shorts.
