Join Alaska Airlines Mileage Plan & get $25 or $50 off your next flight

Update: The $25 offer isn’t available for residents of California, Hawaii or Alaska, but there is a $50 offer for California and Hawaii residents. I’ve added a link to that registration page below; thanks to Nate for the heads up about that one.

Alaska Airlines is offering an incentive for people to join its Mileage Plan loyalty program. If you join before the end of the year, you’ll receive a discount code giving $25 off your next flight provided you book within 28 days of joining the program.

If you live in Alaska, California or Hawaii though, I’m afraid you’re out of luck as residents of those states are excluded.

The Deal

• Get $25 off your next Alaska Airlines flight when joining the Mileage Plan program.
  • Direct link to offer (residents in states other than California, Alaska and Hawaii).
• Get $50 off your next Alaska Airlines flight when joining the Mileage Plan program.
  • Direct link to offer (residents of California and Hawaii)

Quick Thoughts

Many readers will already have an Alaska Airlines Mileage Plan account, but I suspect that there’s a not-insignificant number who don’t. For the latter, getting $25 off an Alaska Airlines flight could be a decent enough incentive to get them to enroll.

However, be aware of the limitations of this offer. If you’re about to book a flight, you won’t be able to use the promo code as that’s not due to be issued until three days after registering. You then have to use the code within your first 28 days of membership for a flight within 90 days.

Residents of California, Hawaii and Alaska are also excluded from this promotion. That’s a shame seeing as that’s where a significant chunk of where Alaska Airlines serves, but I guess they feel like those residents need less of an incentive to sign up. It doesn’t seem to exclude the redemption of the $25 promo code for flights from California, Hawaii or Alaska though, so if you live elsewhere but need to book a flight from one of those states, that’s presumably fine.
