All airlines are cash strapped and many are pulling parts off of sitting aircraft. We've been told this directly by many many carriers, almost all of them are doing it.
As air travel comes back there will be a rush for parts to get sitting aircraft airworthy again.
Additionally, as of right now there are a dozen or so big big RFP's from major airlines on tearing down their fleets, this will help mitigate the requirement for some of these missing parts, but it will still be a big rush.
