What is the Boston Logan code?
The official airport code for Boston Logan International Airport is BOS, designated by the International Air Transport Association (IATA). It appears on flight itineraries, boarding passes, luggage tags, and parking reservation sites.
Knowing BOS—and where to use it—saves time when booking flights, parking, and rideshares at one of the Northeast's busiest airports.
Why Travelers Need to Know the Boston Logan Code
If you’re booking a flight, coordinating a rideshare, or searching for airport parking, you’ll come across the abbreviation BOS. That’s the IATA code used worldwide to identify Boston Logan International Airport.
This code matters beyond the boarding pass:
- When booking flights: Airline search engines use BOS to pull flights to and from Boston.
- On your luggage tags: You'll spot BOS on any checked bag heading to Boston Logan.
- In travel apps: BOS is how Uber and Lyft drivers locate the airport for pickups/drop-offs.
- When reserving parking: Sites like Airport Parking Boston use the BOS code to identify affiliated off-site lots near Logan.
✈️ Traveler tip: Many guests confuse BOS with “Boston South Station” (Amtrak) or Logan Express terminals. But if you're flying, BOS is what you’re looking for.
