I would certainly expect VA to take another 100 pilots. I could believe 150.
Plenty of greybeard retirements coming up, a few SOs and younger FOs see a brighter future at QF, and many of us middle aged captains are looking abroad. Not to mention the growing debt of pilot annual leave and long service leave, and the training pipeline will be open for some months yet.
I have to speak against the assertion that ATR pilots will be there for 5-10 years. That's utter nonsense. Sure people are recruited off the street onto jets before them, but the ATR crew will always hold a higher seniority number. What's the alternative? every recruit gets 3 months on the ATR then moves on?
