American Airlines has filed an application with the US Department of Transportation (DOT) for 17 additional flights to Brazil.
The airline wants to add a second daily flight from New York's John F Kennedy airport to Sao Paulo-Guarulhos and from Miami to Rio de Janeiro-Galeao. It also wants to convert its existing daily flight from Miami to both Recife and Salvador to separate flights five days per week from Miami to Recife and Miami to Salvador.
American would use new US to Brazil frequencies that are available under the countries' open skies treaty for the flights, according to a filing with the DOT. The treaty was signed in March 2011 with full liberalisation occurring in 2015.
The New York to Sao Paulo flight would use seven frequencies that American currently uses for its once daily Miami to Rio flight, while it has requested seven unused frequencies from the 2011 allocation from the DOT to maintain the existing Miami to Rio flight. It has requested seven of the 28 new frequencies that will become available on 1 October for the new daily Miami to Rio flight.
The Miami to Recife and Miami to Salvador flights would use three unused frequencies from the 2011 allocation as well as the seven used by American for its current daily flight.
Airlines can use the US to Brazil frequencies for flights to anywhere in the country except for the crowded international airports in Rio and Sao Paulo. Only certain frequencies from the DOT can be used for services to the two cities.
American plans to begin the second New York to Sao Paulo flight on 1 October with a Boeing 777-300 aircraft, the second Miami to Rio flight on 15 December with a Boeing 767-300ER aircraft and convert its Miami to Recife and Salvador service to separate flights on a Boeing 757-200 on 15 November.
All of the flights are subject to DOT approval.
Delta Air Lines and Brazil's TAM also fly the JFK to Sao Paulo route. TAM flies Miami to Rio as well,
American has the most service of any airline between the US and Brazil.
