LEX is the airport code for which city?

The airport code LEX corresponds to Blue Grass Airport, which is located in Lexington, Kentucky. This airport serves as the primary airport for the central Kentucky region and supports both commercial and general aviation flights. It is significant because it facilitates travel for both residents and visitors to the city known for its rich equestrian culture and historical landmarks.

The other options refer to locations that either do not have a corresponding airport code of LEX or are served by different airports. For instance, Lexington, South Carolina, does not have a major airport associated with a widely recognized code like LEX. Lake Tahoe, Nevada, is predominantly known for its recreational activities and has its own airport codes, while Lebanon, Pennsylvania, also operates under a different code.
