Which city does the airport code TPA correspond to?

The airport code TPA corresponds to Tampa, Florida. This is derived from the International Civil Aviation Organization (ICAO) and International Air Transport Association (IATA) coding systems, which assign unique three-letter codes to airports for identification purposes. In this case, TPA is an abbreviation that is easily associated with Tampa, given the first letters of the city's name.

The other options do not match the specified airport code; for example, Trenton has a different code, as does Nashville and Cincinnati. Each of these cities has its own designated airport code that does not overlap with TPA. Therefore, understanding the way airport codes are assigned and their meanings confirms that TPA is indeed Tampa, FL.
