I love the airport so much. The airport used to be a fun day out in summer holidays as a kid, just me and some mates. We’d catch a bus there and stay the whole day.

Watch all the airplanes from the old viewing deck. Explore the warrens of office hallways, look at the shops. Buy snacks. You could visit gate areas. Lounge in the futuristic waiting areas. Visit the aerospace museum ( which was free )
