The Southwest Companion Pass is one of the most valuable perks in travel because it allows you to choose one person—such as a spouse, family member, or friend—to fly with you for free (plus taxes and fees) every time you book a Southwest flight. Whether you pay with cash or points, your companion can join you on the same flight for just the small taxes and fees, often starting around $5.60 for domestic flights. The pass can be used unlimited times while it’s active, often lasting for the remainder of the year you earn it plus the entire following year, making it an incredible way to save hundreds or even thousands of dollars on travel. ✈️
