"The reason why i ask is because i feel like the aviation industry is very much in trouble with no hope for the future"

I don't see it that way unless the price of oil continues to go up. Myself, I tend to agree with those who say the bubble will pop. But I'd say up to this point, I don't see this cycle any different than the others in that the fortunes of the airlines tend to ebb and flow with the economy. If the economy is in the crapper, so will the airlines be.

Also. Remember there are non-airline jobs in the biz that are quite good jobs.
