I wouldn't at all agree with the previous posts.
A future employer is going to try to assess your ability in the future through what you have done in the past. A strong previous career is a definate assest to you and would give the potential employer a feel for the type of person you are.
If you have spent several years working in Macky Dees when you are +30 prior to training then think again.
If however you have done vocational work, something out of the ordinary or exciting it will give the interviewer something to question you on and bring out the real you.
If however you are satisfied re-locating poo then go ahead. I am just a little suprised somebody even asking the question in their 30's would consider a flying career.
Unless you want to fly rubber dog poo out of Hong Kong?
