Didn't have to wait too long for a bus 5 - 10 mins, but then it said it was just dropping off. However, the driver allowed us to get on as a lot of people were dropped off. The bus then passed another stop and advised the people waiting that he would drop off the rest of the passengers then go back for them. He went round again by which time there was a second bus just in front of us and this one went round X and Y? and our bus. headed to the exit and the airport. In all it took 45 minutes from getting on the bus to getting to terminal 2 which was not acceptable. Date was 16th May around 4 am.
