United, US Airways Form Marketing Pact

UAL Corp.’s United Airlines and US Airways Group Inc., the second- and seventh-largest U.S. carriers, agreed to sell tickets for each other’s flights to help increase revenue.

The alliance effectively extends each of the carrier’s networks and lets passengers connect to the flights operated by the partner carrier.

The airlines sought to combine in 2000 and later discarded the proposal because of regulatory opposition.

UAL shares fell 70 cents to $4.70 and US Airways rose 36 cents to $2.51, both on the NYSE.
