NZ appears to be going down the Seniority path.
Closer to home, Virgin Group, not so much. The Tiger example in Feb pre Corona, of axing fleet specific Pilots (Airbus) vs The List, well it sort of outlines their intentions on this topic going forward.
Whatever works out cheaper for the company is how it will play out.
Cadets/SO are clearly at the bottom of many lists. However, with operators investing millions in these schemes, getting rid of them all makes no financial sense. They will probably be with the company for the next few decades. So if Jetstar and Virgin pull back a large majority of the widebody operation permanently, I don’t think your 3000 hour FO on the A320 or 737 will be affected. Investing millions in retraining 787 Pilots onto the Airbus, compared to just letting them go, and retraining nobody. Sad stuff, but further demonstrates that The List, is only good for Command upgrades.
Experience equals sweet FA.
There is probably going to be large consequences in terms of lack of Pilots from next decade onwards, as many will walk away, many take early retirements, many won’t even contemplate the industry, and the world starts booming again.
