Just for clarification ... Are you calling for pushback and releasing the brake at 1500z. Ramp responds hold your position for traffic. Then you receive actual pushback clearance at 1515z when the alley clears. So your "ramp operations" goes back and adjusts the aircraft "OUT" time to 1515z ?[/QUOTE]
Doors closed, tug hooked up, brake released, beacon on acars says you blocked out. (tug driver moved us a bit). ramp tower holds the pushback for traffic, then changes your out time to match their radio call. our definition of pay is block out to block in, so for long flights it can add up.
