I wonder why do some airlines spend up to 12 hrs for turnround in airports? e.g., Kuwait Airways arrives in London Heathrow in the afternoon, but doesn't depart until the next morning. Is better to congest the airport rather than congesting the airspace?
In such a case, how many hours is an aircraft allowed to spend while parked on the airbridge before being moved to a remote stand? MEA spends about 3 hrs for turnround in LHR. Does its aircraft remain in the gate for all this time?
If anyone has an answer for these questions, plz reply...
