FlyingOW, interesting post. Not sure what you mean regarding 737 time being neither competitive or relevant. Are you aware that Qatar has been recruiting DECs for both the 787 and 777 for some time? If Qatar wanted 737 captains for FO positions then why not simply advertise the fact?
Some people, myself included, are in the holding pool for DEC. Now, if Qatar subsequently deems that 737 time is non-competitive or irrelevant, then so be it. However, to date, I have heard nothing to suggest anything of the sort.
Not so sure there will be a flood of people jumping at the prospect of 5 years in the right seat "gaining seniority".... for the same money you get as a captain in Europe.
