If you’re a Costco member and devotee of either Alaska Airlines or Southwest Airlines, here’s a deal — reported by Nick Reyes at Frequent Miler — you won’t want to pass up.

Discounted Alaska Airlines and Southwest gift cards is offering a discount on e-gift cards from both airlines. The promotion offers a $500 e-gift card on either Alaska Airlines or Southwest Airlines for $449.99. That’s a savings of 10%.

The e-gift cards do not expire. Southwest allows a maximum of three gift cards per passenger on one reservation. Alaska will allow four. Costco imposes a limit of 10 e-card purchases per member per airline. Other restrictions exist, such as the fact that the Alaska cards can’t be used toward premium upgrades. But the offer is a pretty solid way to save when you’re paying cash.

This isn’t the first time Costco has offered discount airline gift cards. Last time around, Costco members could purchase Delta gift cards in-store or online. This time around, the Alaska and Southwest deals appear to be online-only.

Not surprisingly, the discounted Delta gift cards flew off the shelves. Even though this is an online sale, you’ll want to lock in your purchase ASAP since there’s no way to know when stock will be depleted.

Southwest promises a redemption code, sent normally within the hour via e-mail. Alaska’s processing time for the codes is 24 business hours.

Both airlines allow bookings that use a combination of both the e-card and a credit card. Using the right credit card — such Chase Sapphire Reserve or Chase Sapphire Preferred Card — can still get some build-in travel protections.
