Security staff could learn how to provide their service with a little more friendliness. I've never found them rude as such but from time to time a little abrupt. As the airport is in transition from old to new it's hard to give a real opinion as the last few times I've been it's been different on each visit. On the plus side the new bits are clean and bright. On the minus they have lost the great charm of the old airport and the addition of the new shop units in the airside section (that until recently was landside) now cover what little window area there was. I like airports that let you see the planes taking off and landing. The viewing gallery has been gone for some time now sadly closed but still there. No real change to the function of the airport and the passengers ability to pass through that is genuinely noticeable so for me what is mainly cosmetic change may look more modern but it has lost as many points of charm as it has gained in modern appeal. The only real gripe that I think would be the same for most would be the quality of food and its price! Starbucks is the only reasonable place to go. Inbound the walk from baggage reclaim to the exit is a little anonymous by that I mean you walk along a few blank empty corridors that leave you wondering if you've taken a wrong turn! Not a bad airport but room for improvement and I think the planners need to recognise this place had a charm and it shouldn't be buried in a drive to have a bright white clinical looking new layout.
