And those of you like me (longer in the tooth, grey hairs etc) will have seen all this before. Booms in the late 80's, late 90's....then a bust, 911 was the most recent one, in the 70's it was an increase in fuel prices and a downturn in the world-wide economy. This rate of expansion cannot continue, house prices in the UK cannot continue to soar and stock markets do suffer corrections from time to time.
I think we're seeing a bit of a bubble in pilot requirement/airline expansion at the moment. I have no idea what will cause the next downturn but rest assured it will happen. My only advice to anyone is when the music stops, make sure you have a seat and that you've occupied it for some time. I also have no idea if anyone should buy a jet or a TP rating when looking for the first job, why don't you actually ask the airlines/operators?
