There were two guys in my USAir newhire class that were in their mid-50s. I know one guy that guy hired at Delta at the age of 56. No kidding. You're not too old. They used to look at that but not really any longer. Figure out where you could stand living based on the bases of the commuters and start from there. Look at each commuter's junior base and figure on starting there and if you're willing to stay at a junior base you'll have a better quality of life and maybe upgrade quicker. Go somewhere you can upgrade within 3 years or so and you'll be primed when everyone starts hiring again. Won't guarantee you a job but at least you'll be in a good spot.

Good luck.
