Southwest Airlines targets March 2027 for Boeing 737 MAX 7 service

Southwest Airlines plans to begin passenger flights using Boeing 737 MAX 7 aircraft in March 2027, according to an internal rollout document. The new fleet will feature 150 Recaro seats, Starlink internet connectivity, seat power, and larger overhead bins to replace older aircraft.

The rollout timeline indicates that the airline expects to begin accepting a batch of 27 prebuilt aircraft in mid-to-late December 2026, with additional newly built aircraft arriving in February 2027. Preparation work, including configuration and maintenance, will take place at Paine Field, Phoenix, and Kansas City.

Before entering passenger service, each aircraft must undergo at least five flights, including a simulated extended-overwater operation lasting more than 3.5 hours. While the Boeing 737 MAX 7 received FAA certification on August 3, Southwest must still complete its own operating approvals, including training, inspections, and validation flights with FAA personnel.
