is that, at least back when I occasionally flew on them, they didn't do seat selection. And more than once I was travelling with a couple of little kids and had to frantically find someone willing to swap seats so I could sit with them.
I'd pay a fee for seat selection, myself.
The real problem is that airlines have trained people to go for the cheapest possible fare, regardless. A while back a friend was travelling from Albuquergue to Minneapolis and was a bit concerned about the plane change in Atlanta. Why that routing? It was the cheapest fare. Personally, I'm willing to pay a bit more for a more convenient routing. Or time of day. Or even airport. I've decided, since I live in Santa Fe, I will fly in and out of this airport and I don't even look at flights from ABQ, because I can't see driving an hour when I could all but walk to the Santa Fe airport. And the last time my son visited my from the east coast I told him to plan on flying in and out of Santa Fe. He was pleasantly surprised at how convenient it was.
