LR3. For FO they will always find enough pilots. You can allways lower req and call turboprop guys and that will solve the problem. I guess they will not have the same 4000 TT and 2000 Jet req as Emirates. With 1000 or 2000 TT, 500 turboprop you will always find people. But if they pretend to hiler 4000 TT, 2000 Jet guys for FO, yes, they could face a shortage.
DEC would be a real problem. Expats A320 and B737 commaners are in high demand with 8 to 12 K in the pocket and 2 months on, 1 off commuting contracts plus benefits.
They will fly 737NG or A320?
