Etihad Airways is intending to codeshare with Oneworld operator American Airlines from September, giving the Middle Eastern carrier greater access to the USA.
The codeshare agreement, which Etihad says is still subject to US Government approval, would cover American's transatlantic routes from Paris to Boston, Chicago and Miami, plus Dublin-Chicago, Frankfurt-Dallas, Manchester-Chicago and Milan-New York.
It will also include domestic flights from New York and Chicago to Washington, Los Angeles and San Francisco, as well as Chicago-Houston.
American's 'AA' designator code will, in turn, be carried by Etihad flights between Abu Dhabi and New York, Chicago, Paris, Frankfurt, Manchester, Milan and Dublin.
Etihad says the agreement stands to provide access to US cities previously unavailable to its passengers.
"The USA represents a key market for Etihad and one in which we are keen to grow further," says Etihad chief James Hogan.
Etihad only serves one US destination, New York JFK, but is planning to open a new Chicago link from September and the codeshare should come into effect at the same time.
