Qatar taking DEC from 737 onto 78 and have taken many in the past on the same route.
As have EK... there was a time when they turned up at STN, did interviews there and then and took as many RYR 737 skippers as they could take. There are many many ex Ryr and Easy Direct Entry Captains flying wide bodies in the desert.
As the inevitable shortage deepens, as Asia opens up, as the Americans continue offering great packages to their own pilots its only a matter of time before we see this again.
Take the command. Worse case scenario better off an unemployed Captain and be able to go back to RHS if needed.
