Jfk stands for
JFK commonly refers to John Fitzgerald Kennedy, the thirty-fifth president of the United States. It is also the airport code for John F. Kennedy International Airport in New York. A biography and a flight itinerary therefore use the same letters differently.
Meaning and context
The initials come from the personal name, but the abbreviation has become associated with multiple named institutions and places. Read the surrounding information rather than assuming that every JFK reference concerns the person directly.

Examples and usage
A sentence about a presidential speech likely refers to Kennedy. An airline itinerary showing JFK identifies an airport. If a document lists another institution with those initials, use that document’s definition instead of forcing one of the common meanings.
What to check
For travel planning, the airport code is not a complete address, terminal assignment, or schedule. For historical writing, the initials do not substitute for accurate dates and context. Spell out the intended name on first mention when readers may not share the background.
