It’s not often we see an airline run a discount that applies to nearly all of its flights. Sales usually include just a certain number of routes and it can sometimes can be hard to tell if you’re really getting a discount. But from today through December 13, 2019, you can save 10-20% on many Alaska Airlines flights.

Here are the details of the deal:

• Start your search on Alaskaair.com and use the promo code IFLYALASKA
• You must fly on Monday through Thursday to receive 20% off. You’ll receive 10% off if you’re flying Friday through Sunday
• Travel from January 7, 2020 to March 4, 2020
• Book by 11:59 pm on December 13, 2019
• Discounts only apply to tickets in economy class

However, you can save even more with this deal. Currently there’s an Amex Offer floating around where you can get $40 back after spending $200 or more with Alaska. Here’s an example of a round-trip transcontinental flight between Seattle and New York in Alaska’s Main Cabin fare class with the 20% discount applied. It dropped it from the original price of $297 to $243 after applying the code.

But if you used the Amex Offer, you’d save an additional $40, dropping your price to $203.

The promotion appears to be “intended for Starbucks rewards customers only,” but the discount code seems to work for anyone. When searching, you’ll know the discount has been applied if there’s a little red flare next to price of the ticket.

Alaska has also just launched an award sale, dropping prices for mileage redemptions on routes across the country.

If you do end up taking advantage of this deal make sure you pay with a card like The Platinum Card® from American Express or the Chase Sapphire Preferred® Card, that earns bonus points on airfare.

You’ll earn Alaska miles on these discounted flights since they are traditional revenue tickets. If you’re wondering how to earn Alaska Airlines miles, the fastest way is by opening the following cards (which both earn 3x miles on Alaska purchases):

• Alaska Airlines Visa Signature® credit card
• Alaska Airlines Visa® Business credit card
