“EGLL” — Which Heathrow code is this, and when should I use it vs. the passenger code?
I’m cross-checking a flight plan and spotted “EGLL” for Heathrow. Our traveler docs usually show a different three-letter code, so I want to avoid mixing apples and oranges between booking portals, flight trackers, and ops spreadsheets. Can someone point me to a clear page that confirms Heathrow’s codes and explains the context (so the team knows what to put on tickets vs. what shows up in aviation tools)?

This Heathrow page keeps the codes straight and gives just enough orientation that your team won’t confuse operational/aviation usage with the passenger-facing one—great for reducing rework: https://city-info.co/airports/london-heathrow-airport/
