Taxis are available in abundance at the airport and offer lifts downtown, in addition to hotel shuttle services, many of which take visitors to hotels in the central business district of the city.

The first airport serving New Orleans was deemed too small and in 1940, plans for a larger one began, which was to be called Moisant Field, after an aviator who died in a 1910 accident. It became an air base during World War II and developed into a civilian airport in 1946. The airport was renamed after Louis Armstrong in 2001 and faced damage from Hurricane Katrina in 2005 when floods closed down the city of New Orleans, although it soon returned to its functioning standard.
