Which city is represented by the airport code BIL?

The airport code BIL represents Billings, Montana. FAA airport codes, which are used for general aviation, are typically three-letter identifiers that are unique to each airport. In this case, Billings Logan International Airport is assigned the code BIL, allowing travelers and aviation professionals to easily identify the airport within the context of flight schedules, air traffic control, and other logistical operations.

The other options do not correspond to the airport code BIL. For instance, Bilmington is not recognized as a location associated with an airport code, and Boise, Idaho, is represented by the code BOI. Similarly, Birmingham, Alabama, has its own unique airport code, BHM. Each airport is designated a specific code to avoid confusion and ensure clarity in aviation communications. Therefore, recognizing that BIL is specifically linked to Billings, Montana, helps in correctly identifying the airport associated with that code.
