commutable trip.
If they notify you of a trip before 12 hours and you don't acknowledge the trip 3 hours prior you have to be 'promptly available' from original report until 6 hours after.
That is the big question, what is promptly available mean? according to scheduling that means you better be at the airport at that moment to work that flight...or else!
ALPA hotline disagrees and says that means " reasonable report aka 2 hrs ish"
BUT has anyone ignored the calls and at the trip sign in time answered and said, "Ill be there when I can" delayed the flight etc?
Would love to know, cause ALPA never followed up with the follow up in this case.
