I had a late 50s guy in class with me at Eagle in Nov. So you can get hired. Don't go to gulfstream, its a rotten place from the best accounts.
Unlike ryane, I think the FAA will get the age 65 thing done before Bush is out of office. If not, it could be stalled for quite a while longer as the new adminstrator "studies" it.
Having said all that, think about the lifestyle you're getting into. Nobody on these boards complains about flying, just about how we're treated by the airlines we work for.
Four day trips with minimum rest overnights, 2-3 hour sits at airports with no crew rooms, eating airport food, sitting reserve, schlepping a 35# flight kit everywhere. There's a lot of downside to the job.
The upside is the people you fly with, and some really nice views.
