I am currently half-way through doing a back-to-back to Copenhagen. I can't believe there's any airport easier than this: exited jet-bridge and immediately able to turn back on myself and enter the gate-lounge. Had booked myself to return on the 817 (arrived on the 814) but arrived with so much time that I quickly hurried to Departures and the check-in lady put me on the 815 (the same plane) with no hassle. Back through security and sitting in my favourite seat.

I think I'm definitely going to make this my turn-around airport of choice! Too good. Now to work out why I can't select my seat on my flight to MIA tomorrow....
