The website for Louis Armstrong New Orleans International Airport maintains a page listing the fare for taxi rides to the central business district. Alternatively, there are websites such as TaxiWiz.com and TaxiFareFinder.com that attempt to calculate taxi fares between specific locations.
For passengers traveling to the central business district, additional transportation options include an airport shuttle service and public transportation. The shuttles service the major downtown hotels, and the public bus route terminates at the intersection of Tulane Avenue and Loyola Avenue. Fares and directions for use of these services are listed on the airport's website on the same page as the taxi fare.
