I will be flying Alaska Airlines as much as possible from now on! Clean hydraulics under the wing flaps. I used to work on helicopters, so when I see dirty, hydraulic fluid under the flaps, it makes me wonder where else is there sloppy maintenance.? Alaska Airlines were spotless! Friendly staff!

Just not happy our original (nonstop) flight was cancelled and we weren’t able to fly out until the next morning and ended up having a 6 hour layover with 4 kids. They ended up checking our luggage free of charge and we received food vouchers for our layover.
