Also, it doesn’t have to be a flight. And you don’t have to tell Crew Scheduling anything beyond “I will not make my scheduled sign in. Mark me down as a commuter miss”. Then hang up the phone. Just don’t abuse it and it’s a non-event.
”3. Pilots who commute by other means (e.g. automobile, train, bus, etc.) shall also be covered under this policy for unforeseen events, provided they notify Crew Schedule as soon as such events become known, and the scheduled sign-in is no longer possible. Examples of such events include but are not limited to severe unforecasted weather conditions, vehicular accidents and mechanical breakdowns.”
