Alaska Mileage Plan is one of my favorite frequent flyer programs, given their unique array of airline partners, combined with their generous mileage earning rates.
It’s an exciting year for transpacific flights out of Seattle, as next month both Cathay Pacific and Japan Airlines are launching flights to Seattle:
- Cathay Pacific will fly an A350 between Seattle and Hong Kong as of March 31, 2019
- Japan Airlines will fly a 787 between Seattle and Tokyo Narita as of March 31, 2019

This is a logical expansion point for both airlines. In addition to Seattle being a growing market, as well as Seattle being the closest major US mainland gateway to Asia, both airlines also partner with Alaska Airlines, which is based in Seattle.
So to celebrate these new routes, Alaska Mileage Plan is offering double miles on both flights for a limited time.
Earn double Alaska miles on Cathay Pacific
You can earn double Alaska Mileage Plan miles for travel on Cathay Pacific between Seattle and Hong Kong from March 31 through May 31, 2019. Registration is required prior to travel. It appears that previously booked travel qualifies, as long as you register and travel during the promotion period.
Only travel operated and marketed by Cathay Pacific qualifies, and you need to be traveling in fare classes J, C, D, I, W, E, R, Y, B, H, K, L, M, or V. Bonus miles should post within four to six weeks of eligible travel.
For context, here are the usual Mileage Plan earning rates on Cathay Pacific:

Bottom line
If you’re planning on taking either the Cathay Pacific or Japan Airlines flights in the first two months that they’re operating, this is an excellent offer. Alaska already has attractive mileage earning rates for travel on these airlines, so it only gets better from there.
For example, most business class fares on Cathay Pacific and Japan Airlines earn 225% miles, plus elite mileage bonuses of up to 125%, plus an additional 100% bonus with this promotion. That means members can earn up to 450% miles for some of these flights.
Anyone taking either of these flights in their first couple of months of service?
