United Airlines is expanding service by adding two new nonstop flights -- one from San Antonio to Washington and another from San Antonio to Los Angeles, the company said Monday.

Chicago-based United Airlines will begin offering these flights Oct. 31, 2005.

The Washington-to-San Antonio round-trip service will be operated by United Express partner Mesa Airlines using a Canadair RJ-700 66-seat regional jet.

The San Antonio-to-Los Angeles flight will be operated by United Express partner Skywest, also on a Canadair RJ-700 regional jet.

United Airlines offers regional jet service under its 'explus' brand. The airline is working to become more competitive by offering customers more comfortable travel experiences and additional flights, United Airlines' Vice President of Operational Services Sean Donohue says.

The Canadair RJ-700 regional jet is designed to offer more passenger room.

"This latest expansion further reinforces United's commitment to provide quality and comfort to our customers," he says.

United is the world's second largest airline. It operates more than 3,400 flights a day to more than 200 U.S. and international destinations.
