However crews are still positioning themselves prior to the flight despite hotac being made available. Shot foot comes to mind.
In various airlines where pilots are contractors and are based away from home, thus no hotel is provided, nor duty time to commute, this is also not unheard of. Trying to get a home life comes to mind. XAA's turn blind eyes.
Not to condone it, but that's the reality. Who's at fault; the pilot, the company, XAA or all 3?
