“HERE’S THE DEAL” SECTION

Here’s the Deal

Home » Here’s the Deal

We’ve agreed to buy AirTran Holdings, Inc., the parent company of AirTran Airways, one of America’s largest low-fare airlines. We firmly believe that both AirTran and Southwest are stronger together and can accomplish more, faster than either can on its own. The communities we serve will benefit from a stronger and more competitive low-cost, low-fare airline network.

Southwest’s acquisition of AirTran, as proposed, would:

   

Significantly expand Southwest’s low-fare service to many more Customers in many more domestic markets, creating hundreds of additional low-fare itineraries for the traveling public.

   

Generate hundreds of millions in annual savings to consumers.

   

Invigorate competition at Hartsfield-Jackson Atlanta International Airport, the world’s busiest airport, by expanding low-fare service to numerous additional nonstop, direct, or connecting markets beyond those served by AirTran today.

   

Allow Southwest Airlines to expand its small presence in New York City and Boston, and serve the Washington, D.C. market via Ronald Reagan National Airport.

   

With a more diversified fleet, provide Southwest Airlines with the flexibility to consider adding service to smaller cities and communities than it currently serves.

   

By adding AirTran’s current Mexico/Caribbean service, allow Southwest Airlines to evaluate new international route opportunities from direct experience for the first time.

What We’re Doing Now

Home » Here’s the Deal » What We’re Doing Now

This transition will take time. We will, of course, first need to obtain clearance from the U.S. Department of Justice and other regulatory approvals, and AirTran will need to obtain stockholder approval. Following those approvals and closing of the transaction, our plan is to integrate AirTran into Southwest within two years. At the end of that time period, we anticipate Customers will see only the Southwest brand and all employees will be Southwest Employees. We have an integration team which will provide oversight and direction to integrating every aspect of our respective operations.

During the transition, major integration activities will occur, including:

 

   

Onboarding of AirTran Crew Members into Southwest Culture

   

Converting the Customer Experiences to Southwest

   

Establishing a Single Operating Certificate with the FAA

   

Combining and integrating AirTran operations into Southwest

For now, the two companies will continue to operate independently. There will be no changes in how we do business in the near term as a result of this transaction.

What’s Next

Home » Here’s the Deal » What’s Next

The transaction is subject to review and clearance by the U.S. Department of Justice and other regulatory agencies, as well as the approval of AirTran stockholders. Until closing, the two companies will continue to operate as independent airlines.

Again, for now, there will be no changes in how we do business in the near term as a result of the transaction.

Here’s What It Means

Home » Here’s What It Means

By creating a larger low-fare airline with a broader national presence, we believe we will create excellent opportunities for Customers, Employees, Communities and investors.

Spreading low fares farther

If combined, Southwest and AirTran will serve more than 100 destinations, with four new airports planned for 2011. We estimate that this will generate hundreds of millions in annual savings for consumers. These fare savings will result from expanding the well-known “Southwest Effect” of reducing fares and stimulating passenger traffic wherever we fly.

Complementary networks

Southwest serves almost 90 million passengers annually and AirTran carries nearly 20 million passengers a year.

Reflecting the complementary nature of our routes, AirTran serves 38 airports not served by Southwest and Southwest serves 37 airports that AirTran does not serve.

We are interested in serving the great majority, if not all, of AirTran’s current markets.

Some perspective

The decision to acquire AirTran enables immediate and significant growth and positions us firmly for future fleet growth. By adding Atlanta and other new cities, creating the opportunity to boost our profits, we expect to have the financial returns to justify adding aircraft, as well as the Customer demand to add flights.

Nothing changes now

For now, Southwest and AirTran continue to operate independently. We’re moving forward with the confidence that we will have the opportunity to bring these two great organizations together and create a larger low-fare airline with a broader national presence – one that spreads low fares farther.

We both look forward to serving you soon.

For Customers

And above all, we will remain focused on operational performance and safety.

For Investors

Home » Here’s What It Means » For Investors

This acquisition represents a unique opportunity to grow Southwest and take a significant step toward achieving our strategic goals over the next decade.

Despite our success over the past decade, our low-fare brand and business model have been challenged by a volatile economy and skyrocketing energy prices. The decision to acquire AirTran enables immediate and significant growth and positions us firmly for future fleet growth. By adding Atlanta and other destinations served by AirTran not currently by Southwest, we are creating the opportunity to boost our profits and we hope to have the financial returns to justify adding aircraft. We see significant growth opportunities at Atlanta and into our network that will bring more competition, more low fares, and more Customers.

The acquisition of AirTran supports our 15 percent pre-tax investment return requirements. The transaction is an attractive and efficient use of our capital and accelerates our strategy to boost profitability and achieve our financial targets.

If combined, Southwest and AirTran will serve more than 100 destinations, with four new airports planned for 2011. We estimate that this will generate hundreds of millions in annual savings for consumers. These fare savings will result from expanding the well-known “Southwest Effect” of reducing fares and stimulating passenger traffic wherever we fly.

Combining the two brands will create a larger and stronger low-cost, low-fare carrier network, with growth opportunities that do not exist otherwise. We are interested in serving the great majority, if not all, of AirTran’s current markets.

Atlanta

Combining our airlines will invigorate competition at Hartsfield-Jackson Atlanta International Airport by expanding low-fare service to numerous additional markets and one-stop markets beyond those served by AirTran today.

An economic analysis by the Campbell-Hill Aviation Group estimates that Southwest’s more expansive Atlanta service has the potential to stimulate more than two million new passengers and $200 million in fare savings to consumers annually.

New York City and Washington, DC

Because Southwest has more routes in its national network, the combined airline could offer New York City and Washington, DC passengers a multitude of additional travel options and inject needed low-fare competition into these critical air travel markets.
