You might be right about that. I friend of mine is flying for transavia FR, this summer they do have a shortage of FO and he is already hitting the FTL. The situation is the same for other low cost who manage the reduce the crew/plane ratio to the minimum, in order to boost summer profit. This situation can't go on forever; but right now they need cash flow to survive the winter/fall season. After that, if the pandemic is under control, they'll be hiring heavily. There will be shortage of experience crew, but don't fool yourself, there will always be unlimited supply of fresh cadet.
