I would agree 100%,it used to be a brilliant wee airport.
There's no real concept now of having bread and butter routes on gates, bussing is the new norm. The new 15-17 gates are just a corrugated iron bolt-on, but the intrinsic issue for me is that the layout makes no sense. Two International Arrivals areas (take your pick), a domestic arrivals door behind Starbucks, a check in queue stretching into the old arrivals hall and most stressful of all, no clear queuing for check in. It's not fit for 2018, it's really not, and worst of all, there's just nowhere to go without spending a decent amount of money that a purely private EDI would never be able to justify an ROI around.
