Associated Press:

United Airlines said Thursday it agreed with EgyptAir to sell seats on each other’s flights beginning next summer.

The so-called code-sharing agreement lets United sell tickets on EgyptAir flights as if they were operated by United.

United said it will put its name or code on EgyptAir flights from New York’s Kennedy Airport and London’s Heathrow Airport to Cairo.

EgyptAir will put its name on United flights linking Kennedy Airport with Los Angeles and San Francisco, and on flights from Heathrow to Chicago, Los Angeles, San Francisco and Dulles Airport near Washington.

Both airlines are members of a larger group of carriers called the Star Alliance.

UAL Corp. shares fell 78 cents, or 7.5 percent, to $9.58 in morning trading.
