MAN received two diversions this week. Both emergencies, one medical, one technical. The tech aircraft I believe is still there, blocking a remote stand and no doubt giving the maintenance guys a headache. That's the trouble with diversions, you really don't know what you're getting yourself into. A quick splash and dash or a longer protracted stay. At some point they will all need fuel (usually) some sort of tech clearance, maybe spare parts from abroad so customs clearance, a tug and crew, dispatcher, maybe even loaders and cargo handlers. Hotac possibly for crew or/and passengers.
All these are problematic especially at a time of staff shortages. I heard the other day that Swissport are paying £30/hour overtime rates just to get people to work extra hours!
Your 'dynamic' solution at the moment is dead in the water.
