Over the past observed year it logged 1,254 flights totaling 3,179.1 hours, putting it among the more active aircraft in its cohort of 51 still-registered 737-990ERs, nearly all of which also fly for Alaska Airlines.

A JetPhotos listing ties the tail to Alaska Airlines, consistent with the registry, though it does not describe any specific livery scheme. No registration changes or prior tails appear in the record since delivery.
