The crew who fly the 744, what will happen to them? Captains retire or move to another aircraft? In their case, are they looking at pay cuts (and the inevitable hit to FAS)? Are there slots on other types that are available?
And now they're considering mothballing the A380 as this damned virus thing starts to bite. What will those guys (and gals) do?
The retirement of the 747s has been on the cards for a long time, and whilst AJ did bring it forward from the original time, it wasn't a dramatic change.
Of the Captains, at a guess, probably about half will retire. Of the remainder, some are anti Airbus, and would move to the 787. Those who like four engines, and don't like the thought of Airbus, will have sufficient seniority to displace on the 380. That means that they actually push out an incumbent 380 Captain...but one who is junior to them. Perhaps as many as 25% of the 380 Captains would be in danger of such displacement.
Now, they, in turn would look around the fleet, and decide where they would like to go. They're also very senior, and certainly senior to the 330 and 787 people and could simply displace onto whichever fleet they chose.
And now we have displaced 330 and 787 people, who can also displace, but who will start running out of people junior to them in the same rank, so now we have the potential for them to displace to a higher aircraft (be it 787 or 380), but as FOs.
Of course, whilst this command displacement is going on, the same game is happening amongst the FOs, but its worse there, because of the risk of Captains taking a demotion.
So, in this scenario, you could perhaps end up with about 30-50% of all seats needing to be retrained. If you threw in a retirement/reduction of the 380 on top, then it could go to about 100% displacement across the 787 and 330.
The only people who wouldn't end up with a pay cut, would be the ones senior enough to displace from the 747 to the 380, but keep their rank.
I don't understand the reference to FAS.
Of course, nobody planned for the effects of the virus, so the outcome is anyone's guess.
