Quick Thoughts
Some Alaska Airlines sales include niche destinations, but this is a far more widely useful sale than normal seeing as it includes the entire US, as well as Canada, Mexico, and more.
There are a few blackout dates during the 4.5 months that the travel period is valid for, but if you have any flight needs from early January through late(ish) May, it’s worth pricing out flights on Alaska using the THANKYOU20 promo code if they serve the routes you’ll be traveling.
