I can't speak for the "legacy Xjt" side but, at ASA.

On a leg-by-leg basis, a regular pilot who has a trip, or portion thereof, cancelled or involuntarily removed from his schedule for any reason, other than his own illness, injury, leave of absence, retirement, training failure or delay, suspension, termination or failure to report, will be paid and credited his actual flight pay hours or scheduled flight pay hours, whichever is greater. For purposes of this paragraph, “schedule” includes all trips for which a pilot is responsible regardless of the method by which he is assigned or awarded the trip. Once a trip is assigned, it is part of a pilot's schedule.
