Hi vsflight
By now means are you too old . I have a few friends in the business who did not start out till their late 30's
Though I would think long and hard before taking the plonge especially if you have a good job , giving up a good one for one that might never be could turn out to be a mistake you might regret.
The reason I say this is that realistically you will not be qualified to the extent that an airline will employ you in two years
There is alot of young type rated unemployed pilots out there .
At the end of the day if your heart is really in it don't let your age stop you just be prepared for the hurdles.. flightime..
