Southwest To Upgrade Over 800 Boeing 737s

Southwest is about to embark on a major retrofit of its entire fleet as part of a new era for the U.S. carrier.

The retrofit, slated to commence on May 1, will see the airline retrofit over 800 aircraft by December 31 to ensure they are ready to offer Southwest’s new era to passengers.

In an exclusive interview, the Senior Vice President of Technical Operations confirmed the plans to Aviation Week.

At the heart of the changes will be the installation of premium seating and an assigned seat, a move away from the traditional model Southwest has championed for decades.

The assigned seats will be sold from the third quarter and, therefore, operational by the first quarter of 2026, assuming there are no delays in the launch of this process.

Southwest’s undertaking is expected to be colossal, with anywhere between seven and ten aircraft getting the makeover every night in hangars across the United States.

With hundreds of aircraft expected to be involved, this represents one of the industry’s most ambitious cabin retrofit programs in history.

While most retrofits will include more changes than what Southwest is implementing, the sheer scale of the U.S. companies’ endeavours is the most striking, with so many planes equipped with changed seating each night.

A New Era For Southwest

The retrofit program is ultimately just one endeavour the airline seeks to launch as it enters a new era.

Southwest’s new era, which it has publicly discussed, emphasises long-term profitability and sustainability in an evolving industry.

The airline is aware that much has changed in recent years, and because of this, the airline no longer feels its previous strategy will hold up as other companies advance.

Therefore, the US carrier is proceeding with the major undertaking and investment of premium seating to generate additional revenue while abandoning the open seating model.

These two types of flying were pivotal to the airline’s launch and have been a strategy largely since birth; however, Southwest is axing this through fundamental research and analysis of what is best looking ahead.

Analysts who have studied the popular U.S. airline believe revenue can be increased considerably, and decisions like those made inside the plane will help.

Other notable changes include the launch of 24/7 operations. Southwest feels that these nonstop operations allow it to use its assets as much as possible and to its advantage.

Obviously, the longer aircraft spend on the ground, the less money they make. While 24/7 operations might throw some specific curveballs at crew scheduling, they are essential in the long term.
