Alaska Airlines has announced a promotion earning members at least 10,000 miles on paid round-trips between North America and the rest of the world on any of its 15 partner airlines. The promotion runs from March 1 through December 31, 2020.

Alaska Mileage Plan and American AAdvantage are both offering a limited-time bonus when you buy miles. Both deals are a significant improvement over the normal prices, but should you buy? The answer (and which deal is better) depends on your travel plans. Here’s our breakdown of the two offers.

Alaska Airlines has announced a partner award flash sale, with a discount of up to 50% on awards from the US and Hawaii to Australia, New Zealand, and the south pacific with Fiji Airways. The promotion applies to awards in economy and business class and must be booked by February 29, 2020.

There is currently an Alaska flash sale for Mileage Plan members, but it ends at midnight on December 14th. Now is the time to redeem miles for your post-holiday flights! Awards can be purchased from 5k to 15k miles plus $6, but restrictions apply.

Alaska has added the ability to redeem miles on Singapore Airlines, which is great news for Mileage Plan members. But there is also some bad news that largely overshadows the positive announcement: Stopovers on one-way award travel within Asia are no longer allowed.

American Airlines and Alaska Airlines have announced additional cutbacks to an already-diminished partnership. As of March 1, 2020 reciprocal award mile redemptions between the airlines will no longer be available. Additionally, Alaska Airlines Mileage Plan members will no longer be able to earn Alaska miles on international American Airlines flights.

Alaska Airlines now allows you to redeem your MileagePlan Miles on Aer Lingus flights to Dublin and then onward within Europe. Although this option has been around for a few months, it’s worth a closer look at how to maximize your value from the new partnership.

Alaska MileagePlan is running a 40% bonus on purchased miles through the end of the day tomorrow. Although it’s almost never a good idea to purchase miles speculatively, this sale could be an excellent way to buy discounted business or first-class tickets with one of Alaska’s many partner airlines including Cathay Pacific, Emirates, and Japan Airlines.

Alaska MileagePlan is offering a bonus from 20-50% on purchased miles through December 21, 2018. If you maximize this offer, you can acquire Alaska miles for 1.97 cents each.

Alaska Airlines has announced that you can earn double miles on flights from various destinations to its latest airport Everett’s Paine Field. The promotion is valid on flights between February 11, 2019, and March 31, 2019.
