If it was only "erroneous planning " . . . . . . . . . no doubt this phrase will be wheeled out again in the Autumn when they decide a certain percentage of the pilots will be only too happy to take unpaid /unrequested vacation to cater for their oft demonstrated totally inadequate organisational skills.

A much bigger elephant in the room , and a greater part of the recruitment problem, is the change of company culture/mindset towards their employees.
That is a harder one to fix than merely screwing up recruitment numbers.
Not to worry, outsourcing production to go2fly employees will solve everything in short order
