The flight from Seattle to San Diego was delayed due to a maintenance problem. Alaska Airlines kept customers in the loop and even brought in another plane, which was new and nice. The staff handled it well.

Being unable to select seats was annoying, leaving us wondering if we would be split up from our grandchildren. We ended up relegated to the last row of the plane while others were not only selecting their seats but were being upgraded at the same time. Service in the last row, despite closest to the galley, was last to see water provided. Overall OK, some areas need better explanations or offers. I think it is a Delta Airlibes quibble - Expedia is clearly not a preferred partner.
