Quote: "I don't know if it's a ban (I haven't seen it documented anywhere), in fact the night quota restricts numbers of movements without differentiating between arrivals and departures."
Thanks for the info.
Quote: "But it's true that no carriers currently schedule departures before 06:00. BD used to have the occasional 05:55 departure to JED/MED, but it normally left late and rarely got airborne before 06:30."
Makes sense, there would be little demand.
Quote: "It would make sense that those scarce pre-06:00 night quota slots are of more value to airlines for long-haul arrivals than for short-haul departures."
Exactly, and increasingly so with the projected growth of longhaul destinations.
