Pros: Very Quick and efficient Immigration Clearance in PNQ.
Cons: Need to organize Passenger movement from Gate to Aircraft in AUH in the order of last rows windows, middle seat and aisle and so on. Need more busses from Gate to Aircraft in AUH. Simply cannot have a fully loaded Aircraft sitting on tarmac with a defective AC, in this weather for 20-50 mins, if possible delay the departure from the gate itself, instead of the wait in the aircraft. If you are using old depleted aircraft, at least compensate the passengers by pricing properly, instead of charging exorbitant charges.
