Costco Visa eligible travel purchases are airfare, hotel bookings, car rentals, cruise lines, and rideshare services such as Uber and Lyft. Purchases at Costco Travel and other travel agencies also fall under the Costco credit card’s travel category.
There are a number of other transactions that are not considered eligible travel for Costco Visa rewards, such as train and commuter travel fares, bed and breakfasts, timeshares, and campgrounds. Those, and travel-related purchases not categorized with the appropriate merchant category code (MCC) for travel, will earn only 1% cash back.
Cardholders will get 3% cash back on all Costco Visa eligible travel purchases with no limits on earnings. In addition to travel, qualifying dining purchases also earn 3% cash back. Rewards are awarded once a year as a reward certificate redeemable at U.S. Costco locations.
