Alaska Airlines is offering a guaranteed minimum mileage earning of 5000 miles each way when you credit partner flights between North America and any destinations other than the U.S., Canada, Mexico, and the Caribbean.

This offer is valid for travel between March 1 and the end of 2020, and applies across their myriad partnerships: Aer Lingus, British Airways, Cathay Pacific, Condor, EL AL, Emirates, Fiji Airways, Finnair, Hainan Airlines, Icelandair, Japan Airlines, Korean Air, LATAM, Qantas, and Singapore Airlines.

No registration is required and bonus (redeemable, not elite qualifying) miles take 4 to 6 weeks to post. They’ll see how many miles you earn on the trip, and top off to ensure you hit 5000 miles in each direction.

• The cheapest British Airways fares earn 25% of miles flown, so Boston – London Heathrow normally earns just 816 Alaska miles. With this promotion you’ll earn 5000 Mileage Plan miles.

  

• The cheapest Aer Lingus fares earn 25% of miles flown, so Boston – Shannon normally earns 724 miles but with this promotion you earn 5000 miles.

  

This doesn’t just give you a lot more miles than you’d normally earn on the cheapest fares, it serves as a reason to credit those fares to Alaska’s Mileage Plan program.

Alaska is already super generous with earning on premium cabin fares on partners, offering big bonuses as part of the program. But this promotion focuses on delivering the most value to customers flying the least expensive tickets – a real departure in recent times for the industry. But Alaska believes their generous frequent flyer program drives profits.
