John F. Kennedy International Airport (JFK), the largest of NYC’s three airports, is located in the borough of Queens. Providing gates for more than 70 airlines, it serves as a hub for American Airlines and Delta, as well as a home base for JetBlue. Opened as New York International Airport in 1948, it was renamed to honor the assassinated president in 1963. JFK is in the midst of a rolling multi-terminal redevelopment project that added swanky new lounges and other amenities to terminals 8 and 4. Travelers can get a taste of its midcentury heritage at Terminal 5’s TWA Hotel, which occupies the former Trans World Airlines Flight Center, a prime example of space-age futurism designed by Finnish architect Eero Saarinen.
