I use the airport frequently for work travel and it is always fine. Security in particular is often very busy but the staff are incredibly swift and - on the whole - polite and friendly. On my last trip, however, my flight was delayed due to a couple of issues where staff did not know what to do. Firstly, when at the gate, the computer system for checking boarding cards did not work and the staff took a long time to organise what to do before deciding to manually check them. Following that, the pilot could not take off because the same staff were not able to provide necessary paperwork. On return into Newcastle at the end of my working week, we could not disembark the aircraft for a considerable period of time because nobody from the airport came to meet the aircraft, despite the fact we were not early to land; in fact we were very slightly later than planned due to a minor delay at Exeter caused by the Red Arrows landing there. I often leave my car in the long stay carpark when I go off to work - this works really well for me on the whole. However, there are a couple of points I would like to make more generally about my parking experience. I don't expect there is anything you can do about them, but I do want to make you aware. Firstly, it is often quite difficult to find a parking space even though I always book in advance and that can be quite stressful. Secondly, signage on the car parks is not great and it is not always easy to navigate back to the car, especially if returning during the hours of darkness. In addition to the previous point, if you do go down the wrong parking area, there are no pedestrian paths between the car parks so you have to walk all the way back round. Finally, the pedestrian routes from the car park to the terminal building is not good at all; much of it is bumpy or on a lilt which makes it difficult to navigate when pulling a case. Also, there are quite a few areas where the path just runs out. It would also be improved if more marked crossing areas giving priority to pedestrians over on coming traffic would make it safer and easier to use.
