Good to see further increases although Feb & Mar were declines last year so not unexpected.
The plans they have for the terminal should be sufficient I'd have thought for the medium term future. Hundreds of shops aren't going to be added to ABZ due to the nature of the pax. It's something like 55% business traffic and these pax tend to want to get from A to B quickly without messing about in perfume shops. I don't get the appeal of airport shopping personally IMO.
Security is the only area that desperately needs improving urgently. Going through 2 years ago would have taken no more than a few minutes at most. Now, my last few experiences have been a ridiculous 15-20 mins wait.
