In 2026, Costco primarily offers airline travel savings through its Costco Travel division rather than through physical or digital "gift cards" for individual airlines in the way they sell restaurant or movie gift cards. While you might occasionally find specialized Southwest Airlines or Alaska Airlines gift card bundles on Costco.com or in select warehouses (often at a 10% discount), the bulk of their flight offerings come as part of bundled vacation packages (Flight + Hotel + Car). These packages often provide significantly better value than buying a gift card, as Costco negotiates bulk rates with major carriers like Delta, United, and American. For members looking for direct flight discounts, the most consistent "gift card" style product available at Costco is the Spafinder or Uber gift card, which can be used for travel-adjacent services. If you are specifically looking for airline credit, it is best to check the "Gift Cards & Tickets" section of the Costco website, as regional availability for specific airline credits can fluctuate based on inventory and seasonal promotions.
