Airline wants the boarding be completed as quick as possible. I wonder what is the cost for any delay? On the other hand, I want get a dollar value for any delay and see the justification value for any improvement. So, I wonder airline would get additional charge for the gate on delay ? Thanks.
Chain of delays
Being late on departure is likely to cause you to be late on arrival, this has the following immediate consequences:
- you may be delayed even more on arrival in congested airports (e.g. London) if you miss your scheduled landing timeslot, being forced to circle around for, say, 20-30 minutes wasting fuel and time until you're allowed to land; I have been on a flight like that.
- the main immediate effect is that some transferring passengers may be delayed because of this, which may possibly result in costs to you to reroute or compensate them.
- you likely have scheduled the same airplane for the next flight with a minimal turnaround time; and delayed arrival may easily cause your next flight of that same airplane to be delayed (again, I have personally seen delays caused by this)
- you likely have scheduled the same crew for the next flight, and in certain situations that delay may push them over the allowed work/rest schedule, so they are prohibited to fly their next (last in their shift) flight - so you need to rapidly find a new crew for the scheduled flight or cancel it.
For these reasons, a single delay sometimes might cause a chain of other delays or even cancellations, and become quite expensive.
