There doesn't seem to be a flow to the airport you have go to one side to do one thing then to another then upstairs to departure lounge. When we arrived back into Edinburgh was a complete shambles the plane parked quite far away from the arrivals we had to then all squash into buses after being cramped on a flight furthermore we then got to UK border and the queue was literally out the doors. Took us at least 30 minutes to scan our passports through even then people didn't know where they were going which queue to go into staff quite happily stood and watched. Thus I believe held up the rest of passengers. The scanner machines took longer than expected also. Overall for the capital city airport would expect it to be more organised and flowing than it was.
