Southwest Airlines and Bank One have enhanced the Southwest Airlines Rapid
Rewards Visa* program by adding two payment products to their fleet.
Southwest Airlines is also expanding its service to Philadelphia in May,
giving Southwest Visa cardmembers another destination for which they can
redeem their rewards. The Rapid Rewards program, a simple and generous frequent flyer program,
now offers the Southwest Airlines Rapid Rewards Visa Business card and the
Southwest Airlines Rapid Rewards Visa Signature card to make it even
easier for small business owners and consumers to earn travel rewards.

Let’s Get Down To Business

Business owners who travel to and from any of Southwest’s destinations
have another reason to smile. Not only will Southwest Airlines Rapid
Rewards Visa Business cardmembers receive two Reward Dollars for every
dollar in Southwest purchases made with the card, they will also receive
one Reward Dollar for every dollar in all other card purchases such as
shipping costs and office supplies.

In addition, business owners will receive the added benefit of simplifying
their finances through:

—Employee cards with spending limits assigned by the business owner.—
Accrual of Rapid Rewards Credits for Reward Dollars earned on employee
cards issued on the business account.—Itemized monthly statements and
online reporting.—Expense management reports identifying business
expenses by employee and merchant type.—Free additional cards for
employees.—Unlimited Reward Dollar earning capabilities.

“Business travel has been a major focus for Southwest Airlines,” said
Joyce Rogge, senior vice president, marketing, for Southwest Airlines.
“This new business card is a great enhancement for small business owners
as they can separate business and personal expenses while also earning
rewards toward Southwest travel.”

The Signature Says It All

Consumers may double their pleasure by using the new Southwest Airlines
Rapid Rewards Visa Signature card for their Southwest purchases, without
an increase to their annual fee. They will earn two Reward Dollars for
every dollar in Southwest purchases—versus one Reward Dollar on the
existing Southwest Airlines Platinum Visa card.

“We’ve enhanced our Southwest rewards structure to help consumers earn
award travel even faster,” said Hugh Bleemer, executive vice president for
Bank One’s card services division. “Consumers want more from their rewards
cards without having to invest more and that’s exactly what we’ve given
them with the new Signature card.”

Business and Signature cardmembers will receive the following benefits:—
Two Reward Dollars for every dollar in Southwest Airlines purchases
(excluding Southwest Airlines Vacations(R) purchases).—One Reward
Dollar for every dollar in everyday purchases.—One Rapid Rewards Credit
for every 1,200 Reward Dollars earned.—After earning 16 credits in 12
consecutive months, receive an automatic roundtrip Award valid to any of
the destinations Southwest Airlines serves.—Limited blackout dates and
no seat capacity restrictions for Award travel.—Low annual fee.—Zero
liability for unauthorized purchases.

Southwest Airlines Rapid Rewards Visa Signature cardmembers will also
receive emergency card replacement, personal concierge service, 24-hour
roadside dispatch, $1 million travel accident insurance, auto rental
insurance coverage, purchase security and travel and emergency assistance.
