"Water exists."

Airport security: "What the fuck did you just say?"

What did the north tower say to the south tower?

"Let’s talk later, I gotta catch a plane."

I would like to complain about the new sushi restaurant at Gatwick Airport. Although there were large portions going round on the conveyor, they did taste a bit like luggage.
