US Airways is stepping into the fray as the battle for transatlantic business hots up.
US Airways has joined merger partner American in its transatlantic tie-up with fellow Oneworld alliance members British Airways, Iberia and Finnair.
On Monday US Airways became the newest member of Oneworld, having left Star Alliance a day earlier.
A statement said US Airways will contribute an additional 28 routes between North America and Europe to the joint venture.
It also said US Airways will join as an affiliate member until it fully integrates all operations with American Airlines.
US Airways operates its own hubs in Charlotte, Philadelphia and Phoenix.
Together, the joint venture will now be able to operate non-stop flights to 18 European cities from North America.
It gives US Airways the ability to jointly set fares, coordinate schedules and market the combined services and split revenues with the other members.
American CEO said that the alliance now has "twice the scale" of the Delta-Virgin alliance, its closest rivals in the transatlantic market.
Delta Air Lines recently began a codeshare agreement with Virgin Atlantic aligning ticketing and flight operations on transatlantic routes.
