I started looking into doing my ATPL when I was 30, started course the same year, graduated age 31 and still looking for work age 32. I actually believe my age and work history will count strongly in my favour when the market picks up again, especially when compared to guys 10 years or more younger (no offence folks). My experience so far is that airlines are still quite receptive until you reach mid-30's and then it gets noticably harder, but many guys out there have proved it is still entirely possible to succeed big time.
Don't regret a minute of it, but given the current employment prospects and the slightly shorter remaining career span once into your 30's I would think twice about making the very substantial outlay involved if you are having to borrow the full cost of a course (and 14-15 months living expenses!). If you already have a wad behind you from a number of years working, then the pain may be bearable enough to give it a go.
Let's just hope things are rosier for you in 18 months than they are for some of us at present.
Good luck whatever you do.
