Southwest Airlines Launches Limited-Time Companion Pass Promotion — Southwest Airlines Co.

Event summary

Southwest Airlines launched a promotional Companion Pass offer for Rapid Rewards Members on August 3, 2026.
Eligible members can designate a companion to fly free (excluding taxes and fees) on qualifying flights from January 5 through March 3, 2027.
To qualify, members must book one qualifying round trip or two one-way flights by August 6, 2026, and travel by November 18, 2026.
The promotion aims to drive loyalty and engagement in the Rapid Rewards program.

The big picture

Southwest's Companion Pass promotion is a strategic move to boost off-peak travel demand during the slower January-March period. The airline carried over 134 million customers in 2025, and this initiative aims to maintain momentum while differentiating itself in an increasingly competitive domestic air travel market. By leveraging its Rapid Rewards program, Southwest seeks to deepen customer loyalty and drive incremental revenue through companion fares.
