It is impossible to say what the end result will be. For the next 12 months there is no return to a normal operation likely. And the time after that depends on the virus - will there be a vaccine, will the virus mutate?
That is a very good point - most decisions taken now should be short term and emergency action. Airlines should not cut too deep as to weaken its capability to come back once the industry starts to recover. Decisions made now need to be reviewed in about 5 or 6 months. Airlines are now fighting to survive - some actions will need to be extreme!
In a drop of demand, airlines must respond quite quickly. Cash is king in a down draft, an airline must cut expenses fast to keep a cash cushion. But the cuts come in 4 durations.
a) Lightest effect / Least disruptive - reduce frequency from say 8 flights /day per aircraft to 6 flights. Works OK in the beginning of a change while the scope can be assessed..
b) Short Term - place aircraft in standby to active storage. Keep maintenance going - use each frame at least 1x week to keep maintenance current. More expensive than (a) but reduces capacity a lot. Works for 1 to 3 month durations, but more expensive.
c) Medium Term - Longer term storage but the ability to bring back relatively easy. So a 6 to 8 month solution.
d) The Desert - Long term storage where the plane may be stored for years.
So EK will soon be where 10 A380s are in (a), ready to serve destinations on a full or reduced frequency. 20 in short term, hoping they will rise to (a) within a few months., 40 going to medium term where service should resume in about 6 months and 40 being parked in the Desert because it is unknown if they will be out 2 year or too long to return. 40% going to the desert is about right.
