American Airlines and LAN Ecuador have received regulatory approval to begin codesharing on each other's flights.
Under the deal, American will place its code on LAN Ecuador's flights between New York John F. Kennedy International airport and Guayaquil, as well as its Miami-Guayaquil and Miami-Quito flights.
American will also codeshare on five domestic LAN Ecuador routes.
In exchange, LAN Ecuador will codeshare on American's Miami-Guayaquil and Miami-Quito flights and its connecting flight between Miami and New York JFK.
"By strengthening and broadening our relationship with Oneworld partner LAN, we are able to offer our customers more travel options and are better positioned to deliver enhanced benefits across our respective networks," said Kenji Hashimoto, American's VP for Strategic Alliances.
American also plans to codeshare with Uruguay's Pluna, which applied to the Department of Transportation late last year for approval.
