Best customs experience was flying into Reykjavik. Walk down empty hallway to customs agent, they flip open your passport, flip it closed, and hand it back.<p>Speaking of LHR, I was amused when I flew there 6 weeks after September 11 2001 (remember, air travel took quite a hit), on a BA 747, and they offloaded us with a stair car and a shuttle bus. I couldn&#x27;t believe they couldn&#x27;t even find enough terminals for their own national airline.
