It appears that indeed the airport will go ahead with a temporary drop off zone in what will later become the car hire centre. This temporary zone will be located close to Taxiway Delta and next to the the proposed second multistory and will open in May, which will mean a major walk for all passengers.
Work on the the second multistory appears to be scheduled to start in June.
The short term car park which will accommodate both the temporary DOZ and the second multistory is now empty with the passenger bridge closed off.
