Isn't short haul overcrewed and training facilities at max capacity? Can there be a requirement for DEPs at present when there isn't capacity for FPP cadets?
I don't know exactly how the bidding system works though. If there's an unexpected requirement for LH pilots in the time between bids, do they then go back down the bid list to those who were just below the cut off at bidding time and offer them the slots? Or do they seek suitable external candidates?
