Aces Low for what its worth I got my first commerical flying job at 36 (Biz jets HS125), the first company before that to offer me employment went bust on the day I joined!) Be prepared for the unexpected, especially in todays depressed market.
Im now at the age of 43, and a TRI/TRE with a large scheduled airline, however, it took me nearly 2 1/2 years to get full time employment. Despite your age if you have good exam results and a first time pass at the IR that maybe that will flag up some interest when conditions get better. (You also need to be very good at selling yourself!)
As an examiner what I will say is that if it has taken multiple attempts to pass your written exams, GFTs and the IR etc then airline flying may present an uphill struggle. All best wishes and good luck!
