United Airlines Expands Codeshare

United Airlines (BULLETIN BOARD: UALAQ) today announced a significant
increase in its codeshare flights to and from Vietnam. New codeshare
flights operated by Asiana Airlines are available for sale immediately,
and additional codeshare flights operated by Thai Airways will be
available for sale beginning Thursday, February 5, supplementing existing
codeshare service to Vietnam with All Nippon Airways (ANA).

Additional flight options will be available on five weekly flights from
Seoul (ICN) to both Ho Chi Minh City (SGN) and Hanoi (HAN) with Asiana
Airlines. United customers will also now have access to daily service to
both Ho Chi Minh City and Hanoi via Bangkok (BKK) with Thai Airways. These
new services complement the existing four weekly flights from Tokyo (NRT)
to Ho Chi Minh City offered with partner ANA.

“We are pleased to expand our codeshare service to Vietnam, giving our
customers more options than ever when traveling to the region,” said
Graham Atkinson, senior vice president - Worldwide Sales and Alliances.
“With more members in Asia than any other alliance grouping, United and
our Star Alliance partners are best-positioned to offer customers the most
access to this rapidly growing market.”

The Air Services Agreement (ASA) formalized between the US government and
the government of Vietnam in late 2003 permits expanded codeshare flights
to Vietnam by US carriers and their partners. United is taking full
advantage of the codesharing provisions allowed under the new ASA by
expanding codeshare flights to and from Ho Chi Minh City and Hanoi from
the current eight flights per week with two partner carriers, up to 56
weekly flights with three partner carriers.

United and United Express operate more than 3,400 flights a day on a route
network that spans the globe. News releases and other information about
