Last month Southwest Airlines (SWA) implemented at Texas’ San Antonio International Airport an adjustment to its open-seat-assignment policy as part of broader efforts the airline has made during the past year to test more organized methods for boarding passengers.
In this most recent program, SWA continued its policy of providing to each traveler a letter that placed them into a particular group for boarding. Additionally, travelers were assigned a number that designated their place in line within each boarding group, in an effort to continue to refrain from assigned seating, while bringing more order to the boarding process.
Initial boarding and seating procedure pilots were conducted at San Diego International Airport in 2006. Any permanent procedure changes SWA chooses to implement will be announced later this year.
