Southwest Airlines is bringing back its Companion Pass promotion, which allows certain customers to take someone for nearly free on unlimited flights.

Generally, the popular promotion requires travelers to book 100 qualifying one-way flights or earn 135,000 qualifying points, and they’ll earn a Companion Pass for the remainder of the year and the following full calendar year. 

But for the latest offer, Southwest is running a flash promotion in which customers can earn a two-month Companion Pass by booking one round trip or two one-way qualifying flights.

Here’s what to know about the new deal:

All the companion has to pay are the taxes and fees for the flight, which start at $5.60 one-way. 

Members can also change their designated companion "up to three times while they have the promotional Companion Pass," the airline said.

Typically, eligible flights must be paid in part with cash to earn a promotional Companion Pass, according to The Points Guy. But for the latest promotion, Southwest flights booked solely with Rapid Rewards points also qualify, according to the deal’s terms and conditions. 

Southwest to start assigning seats, offer extra legroom and redeye flights

In a move announced in July, Southwest said it plans to start assigning seats to travelers, as well as offering premium seating for customers who want more legroom — breaking a 50-year tradition for the carrier with the open seating model.

The carrier also announced that it would offer redeye flights for the first time as well, with nonstop routes from Las Vegas to Baltimore and Orlando; Los Angeles to Baltimore and Nashville; and Phoenix to Baltimore. 

Southwest said its first overnight flight will land on Feb. 14, 2025, and it plans to phase in additional redeye flights over time.
