Welcome to PPRUNE mate.
I didnt get my first airline job until I was 32, and know a number of people older than me that also got their first job in their 30's.
4015 is spot on with his/her advice. The industry has changed so much over the last few years and is continuing to change, so it is difficult to advise you.
If you have the drive, determination, passion and financial stability, I would go for it, life is too short to think 'what if?'. It wont be easy, but the personal rewards and job satisfaction is worth it. Only my opinion of course, but I love the job.
All the best with what you decide and enjoy that PPL!
