Great post! With this post and the previous "line flying" article by the Ryanair pilot, not sure why anyone would want to fund expensive flight school and then end up flying such exhausting LCC schedules through retirement. Sounds bloody awful. LCCs are a good stepping-stone for experience and then finding a job with better QOL.
BA and VS have their issues (especially ultra-long upgrade times), but the flying sounds far less taxing than what you find at Easy/Ryanair, etc...
