Training capacity and productivity are two good old friends. Having been involved with a rather minor role within airline recruitment in much less turbulent times than those, I kid you not that the lead time for any planned boost in capacity is in the order of months, not weeks. Even if there are enough qualified pilots out there who will put in enough applications within 24 hours of recruitment being announced. Things to factor in are lead time for assessment, possible notice period of the candidate to another employer, availability of sim slots and TRI/TRE for the conversion courses, availability of theoretical courses, possible security vetting of the candidate on part of the competent authorities, availability of line trainers, roster robustness and whatnot else. So, I don't know when the 80% productivity mark can plausibly be exceeded under the circumstances, but it certainly cannot be done overnight. Especially in a large company where 20% of the workforce translates into close to 1000 pilots and cabin crew.
