Recently used this airport having not been here in about 5 years. They have done a major upgrade since then. I arrived on a Thursday evening and was off the plane and in my hire car in a matter of a few minutes - all good and smooth. The terminal is small so it was easy with the rental cars right outside the front door. However the return journey the next day was the exact opposite. I checked in and went to the Security Screening area. I was flying Business Class and was delighted to note there was a separate lane for Business/Platinum passengers especially as the queues were enormous. However despite the red carpet and gold railings for the priority queue this system was not being manned and this entry point was one of the two that had the enormous queue. I tried to get towards the front to see if the staff would push me through but they were far away and ignored you. I saw several other people try to find the entrance to the "fast track" security clearance but it did not work for them either. Normally this would be nothing more than an irritant but on this occasion it was a lot more than that. The queues were enormous and after spending 20 minutes in the queue my flight was starting to board and I had to ask to be let to the front of the queue which the people in front were agreeable to. I estimate it would have taken about another 10 minutes to clear Security otherwise i.e. a total of 30 minutes. Normally to get to the Gold Coast I fly to Brisbane and hire a car - I will return to that and recommend others do the same.
