Why is aiming for a 737 job too high? Airlines have to employ a certain number of FATPL people (i.e low hour).
Why dont you aim to fly the Concorde ( oops thats gone ), hmm lets say the B744 or B777 or a A346... Is that too high?
It is in "my" opinion shared by many that the pilot career should be a progressive one.
The only reason why some airlines hire low hour pilot, its because they are "cheap"...
Has for the FI job ( depending on personal/private situation ie: no kids etc... ) i would go anywhere. No pain no gain, if you wany to be a pilot sacrifices have to be made.
