Separately, American announced that it has signed code-share agreements with LATAM Group's TAM Airlines and LAN Colombia.
The carrier said it will add a new route between Dallas/Fort Worth Airport and Bogota, Colombia, in late 2013, as well as new service between Miami and Curitiba and Porto Alegre, Brazil.
American previously had a code-share agreement with LAN, which is part of its Oneworld alliance, but it did not have an agreement with TAM. LAN and TAM merged this year to create LATAM.
Also, regional carrier American Eagle said its dispatchers ratified a new agreement with the company.
The dispatchers, who are represented by the Transport Workers Union, were the only union group at the AMR subsidiary that did not have a new, cost-cutting contract.
“Achieving labor cost savings was an absolute necessity for the company, and this marks a huge milestone as we now have ratified agreements with all of our union work groups,” American Eagle spokeswoman Andrea Huguely said in a statement Monday.
