I was in a similar position like you guys are now.I finished my training at the age of 33 and couldn't even get an interview with only 300 hrs and a surplus of pilots on the market with thousands of hrs experience.I was 3 yrs down the line and 45K poorer and so about 9 yrs ago I decided to mortgage the house and get a 320 rating.I was told that with my experience I would find it extremely difficult to get hired and that I was wasting my money.I figured that if I was to have any chance at all of any kind of flying job I had to give it a shot no matter how small the odds.Sure enough I didn't get a look in for a further 2 yrs but out of the blue came my lucky break where an operator based at LHR needed a type rated pilot to start within 2 days. I was ready even though my IR wasnt current and had only flown a handful of hrs on light A/c during that time. In my experience you need to make your own luck and make yourself as employable as possible to try and get to the front of the queue.I was nearly 38 when I got my first flying job and straight onto jets. I followed my gut feeling, if I hadn't I may have been left on the kerb.Once you get 500 hrs commercial experience behind you then you are in the system and will seldom look back. My advice is if you can afford to take the chance do it because it may just give you the edge.
