ATA Airlines, Inc. today
announced the list of cities included in its codeshare alliance with
Southwest Airlines . During the first stage of the codeshare alliance,
passengers who connect at Chicago-Midway Airport will have the option to
travel from one carrier to the other identical to a single carrier
connection. “This codeshare alliance is the first of its kind for low-cost carriers.
It is a historic move for ATA and Southwest as customers from both
airlines are gaining access to more destinations while both airlines will
be able to grow without the added complexity of having to open new
markets,” said George Mikelsons, ATA’s Chairman, President and CEO.

“We’re excited about the opportunity the codeshare gives us to offer
additional destinations with our famous low fares to our Customers and
bring additional traffic and revenues to Southwest Airlines,” said Gary
Kelly, Southwest’s CEO. “Concurrently, we can continue to grow our
aircraft fleet, planned at 29 net additional aircraft in 2005, and expand
our route system about 10 percent. We are thrilled about our previously
announced expansion at Chicago-Midway.”

When the codeshare becomes available for sale on Sunday, January 16, ATA
passengers can book travel beginning on February 4 to more than 40
