If youโre holding on to Alaska Mileage Plan miles, youโll know that award changes and cancellations are free up till 60 days before departure. Any changes or cancellations within the 60 day period attract a fee of US$125.
However, from 5 June 2018, Alaska will charge the US$125 fee regardless of time to departure. If youโre used to KrisFlyerโs low service fees (even after the new structure came into place), youโll find this pretty steep, although itโs still lower than other US airlines.

The upshot of this is itโs no longer realistic to book a speculative Mileage Plan award and keep kicking it down the road before the 60 day period.
How do you interpret these 2 sentences though?
โThis policy update will be effective for tickets purchased or last exchanged on or after June 5, 2018.โ โ tickets bought before 5 Jun continue to enjoy free changes effected more than 60 days before travel?
โChange/cancellation fees do not apply to refundable fares, whether purchased, award, or Money & Miles.โ โ award tickets generally arenโt affected by the change?
yes, if you buy before 5 june itโs good.
