JetBlue Airways, which has signed its 20th code-share agreement, this time with Air China, reiterates that it prefers to expand its international partnerships instead of joining an alliance.

“It is similar to our agreement with Emirates [Airline],” a spokesman for the New York-based carrier said. “This is our way of dating responsibly.”

The Air China agreement allows the Chinese carrier to put its designator code on JetBlue flights out of New York’s John F. Kennedy International and Los Angeles International airports. The Emirates deal is only for flights from JFK.

JetBlue also has recently initiated partnerships with Hawaiian Airlines in New York and Japan Airlines in Boston, to gain feed for their long-haul flights.

Air China offers a daily flight from Beijing to New York, and two a day from Beijing to Los Angeles. It operates Boeing 777-300ERs on the Los Angeles flights, and will add this type on its New York route Oct. 1.
