Mr. Driver Dear Sir,
Everyone understands your bitch, and it is a valid one, however you obviously have no idea how things happen in the Magical Kingdom of Dubailand. This isn't Heathrow, or any major airport in any first world state, it is Dubailand.
Remember the Golden Rule. The man with the gold makes the rules.
Your big boss, point blank refuses to accept slot times, Premium pricing, CFMS etc. etc.
Therefore if "YOUR" Scheduling people continue to programme 20 or more arrivals in a 30 to 40 minute time frame, and allow everyone else to arrive at the same time what do you expect.
