Airlines will consider you on your merits and qualifications. Basically if you have all the right bits of paper they will then look at your personality and experience coupled with your "portable skills" (ie management experience, PC skills etc). 31-32 is most certainly not too old.
For some odd reason many of the Dutch schools won't accept people on to their courses if you are over 28. Seems bizarre to me, but there you go thats the way it is.
