Alaska Airlines announced today that Singapore Airlines will be its newest Global Partner. Members of Alaska Mileage Plan and Singapore Airlines KrisFlyer loyalty programs will begin earning miles on each other's flights beginning Sept. 27. Mileage Plan members will be able to redeem miles for travel awards on Singapore Airlines-operated flights at a later date.

In addition, the two carriers will enact a codeshare partnership, pending government approval, which will allow guests booking through Singapore Airlines to travel on both airlines and enjoy seamless reservations and ticketing, one-stop check-in, baggage checked to final destination and coordinated flight schedules.

"We're very proud to add an airline of the caliber of Singapore Airlines to our portfolio of Global Partners," said Andrew Harrison, chief commercial officer for Alaska Airlines. "Our guests will enjoy truly distinctive inflight service when traveling with Singapore Airlines, while also taking full advantage of their Alaska Mileage Plan benefits when traveling from the West Coast to Asia."

Virgin America guests have enjoyed frequent flyer benefits with Singapore Airlines since 2013. Alaska Airlines Mileage Plan will take over as the singular loyalty program for Virgin America flyers starting in 2018.

"Our new partnership with Alaska Airlines enables us to improve connectivity between Singapore and the important North American market, providing customers with more codeshare destinations and enhanced KrisFlyer benefits. It also reflects our commitment to continuously expand our network reach and offer our customers greater flexibility when planning their travel itineraries," said Tan Kai Ping, Singapore Airlines senior vice president marketing planning.

Known for its premium inflight service as the world's most awarded airline, Singapore Airlines flies from Alaska's San Francisco hub to Singapore nonstop and via Hong Kong, and from Alaska's Los Angeles hub to Singapore via Seoul or Tokyo (Narita), with connecting service from Seattle and Portland. In all, Changi Airport-based Singapore Airlines flies to over 60 destinations in more than 30 countries on five continents worldwide.
