What city is associated with the airport code MDT?

The airport code MDT corresponds to Harrisburg International Airport, which serves the capital city of Pennsylvania, Harrisburg. This code is part of the IATA (International Air Transport Association) airport code system, which assigns three-letter codes to airports around the world for ease of identification. MDT is specifically linked to the airport’s location and is commonly used in flight itineraries, ticketing, and baggage handling.

The other options do not relate to the correct airport code. Middleton is not a major airport location and lacks an associated IATA code. Minneapolis is served by Minneapolis-Saint Paul International Airport with a different code (MSP), and Middleburg, Virginia, does not have a significant airport with an IATA code that matches MDT. Therefore, Harrisburg, Pennsylvania, is the accurate association for the airport code MDT.
