Although not aligned with any of the three major alliances - oneworld Alliance, Star Alliance, and SkyTeam Alliance - Southwest Airlines does engage in a number of codeshare agreements and partnerships. A key partnership is with AirTran Airways.

Southwest will introduce global airline partnerships. Starting in 2025, Southwest Airlines intends to start formalizing partnerships with international carriers, in order to connect customers with more global destinations, to generate additional demand for travel across the Southwest network.

Icelandair and Southwest Airlines have signed a Memorandum of Understanding (MoU) to initiate a bilateral partnership in 2025. The partnership will allow customers to easily connect between the two airlines’ networks. Icelandair will become Southwest’s initial airline partner.
