What is the bos airport code?
The bos airport code is the IATA code assigned to Boston Logan International Airport, a major aviation hub serving the city of Boston, Massachusetts. In practice, “bos airport code” refers to the three-letter identifier you’ll see on boarding passes, luggage tags, flight boards, and travel itineraries.

When people talk about the bos airport code, they are typically referring to BOS, the IATA designation that most travellers interact with directly.
The BOS airport code, IATA, ICAO, and other identifiers explained
IATA vs ICAO: what’s the difference?
Two of the most common systems you’ll encounter when dealing with the bos airport code are the IATA and the ICAO. The IATA (International Air Transport Association) assigns three-letter codes to airports worldwide. These are the codes you see on tickets and luggage labels. For Boston Logan International, the IATA code is BOS. The ICAO (International Civil Aviation Organisation) assigns four-letter codes used primarily by air traffic control and airline operations; for Boston Logan, the ICAO code is KBOS. Practically speaking, BOS is the everyday “busier traveller” identifier, while KBOS is used behind the scenes and in official flight data exchanges.
FAA LID and other regional identifiers
In the United States, some airports have an FAA Location Identifier (LID) in addition to IATA and ICAO codes. For Boston Logan, the FAA LID is BOS as well. This means that on domestic flight plans and certain aviation databases, you may encounter BOS across multiple systems. The alignment of BOS across IATA, FAA, and common travel interfaces makes it straightforward for travellers to recognise Boston Logan’s code across different contexts.
