Guys,
sorry to be the party pooper here but use your common sense please.
EY has 100+ airplanes on order and at the moment you allready have an FO shortage. Do you really think all upgrades can/will be done from the inside?
Forget it!
DEC will be needed for many years to come. Sure, internal upgrades will continue/increase but it is impossible to go without an influx of DEC!
Same thing happened/is happening at QR. Same promisses where made, same !!!! we are in!
