Happy to see it. Baggage times in SEA were BRUTAL for a long time. Lately they have been on the ball. So, overall, good incentive for DL baggage to get it done quickly. I know they are already scanning the bags as they get put on the belt (when you check the app it says: delivered to carousel __).
But...we know how the "Best Fare Guarantee" works. I'm not gonna hold my breath for any extra miles or $, but HOPEFULLY if nothing else they move quickly with it.
