Southwest Airlines is back with another great chance to earn a limited-time Companion Pass: buy-one-get-one flights whether you book with cash or points. Just book by next Thursday and fly twice by the end of March, and you’ll earn a two-month Companion Pass valid from early August through early October!

Promo details:

  • Register for this promotion.
  • Book one round-trip flight or two one-way flights by February 20, 2025, for travel through March 31, 2025.
  • The earned Companion Pass will be valid from August 7, 2025 through October 8, 2025.

Key terms:

  • This promotion applies only to new bookings made during the promo period, and qualifying travel must be completed during the travel window.
  • Bookings or flights made before registration do not qualify for this promotional Companion Pass.
  • Itineraries booked with a mix of cash and points also qualify for this promotion.
  • Changes to your itinerary are allowed during the promo period, as long as the qualifying flights are completed within the travel window.

Although the Companion Pass is only valid for two months, it’s still a rare opportunity for travelers planning to fly between August and October and save on travel costs. Southwest runs promotions like this every year, and if you can find cheap flights, it may be worth trying whether you book with cash or points. Don’t forget to register!
