Heathrow Airport
From Jenny Everywhere Wiki
In many universes Heathrow was the oldest and most famous of the airports serving London.
Jenny Cornelius was briefly inconvenienced by a traffic jam on the M4 near Heathrow. (PROSE: Birds and Snakes)
The Odds once traveled from New York City to England by commercial airline and were greeted by a Scotland Yard police officer, but were not explicitly shown to land at Heathrow. (COMIC: Battle of Britain)
