It sounds like you are looking for reasons to not go airlines. And really want to stay in. Also that you want security, which staying in provides.
Nothing wrong with that. God knows someone needs to stay in. Unless you die in uniform, everyone gets out eventually--ensure you prep.
Recession, who knows. Sooner or later one will come. When and how bad? If I knew that I wouldn't be flying planes.
Don't forget retirements. Unless the majors want to shrink, they have to keep hiring to replace those forced to retire.
