Crew was very friendly. Our bags showed up at the carousel within 20 minutes of arrival.

Flight was delayed and hour due to tire issue. First flight of the day, this issue should have been discovered prior to boarding.

Both legs of the trip were delayed about an hour. Planes were new, liked the WiFi availability and entertainment available. Crew was very good. People were happy and helpful. Liked the pilots - they provided updates throughout the flights. Snacks were underwhelming. Drinks were good! Like the smaller sodas and they actually came through the cabin 2x which was great. In Seattle airport the construction caused much confusion for Alaska. Process of printing own tags, etc was chaotic for people who didn’t check in online prior to arrival which in turn caused issues for those who did. Plus airport gates were too small for the number of people flying.

We did have to wait an hour for the runway to be cleared but other than that it was fine.

My seat row didn’t have tray tables which made it pretty difficult to get comfortable on a four hour flight. Good experience outside of that, though.

TERRIFIC! Thank you all. Jason Robert Kidwell My favorite flight attendants.

There was no sitting place in Sea-Tac airport. Even airline didn’t provide any food or dinner. I will never take this airline in my future travel.

Crew was very rude and uncaring. When someone tried to place their bag in overhead bin and they asked for help, crew told them they could not assist. Crew member then told the customer if they couldn’t place into overhead bin on their own, they should have checked in bag. When other customer helped to place the bag in the overhead bin, they were given evil look by crew member and told to hurry back to their uncomfortable middle seat. This was despite the fact that the plane did not leave until 30 minutes later. The flight was ~80% full; when final people boarded, they were forced into middle seats with no room for comfort. There were a handful of emergency row seats unoccupied. When asked if any of the emergency row seats may be used, the crew said that they would cost extra. Normally if a flight is completely boarded and there are open seats, the crew at least gives thought to asking someone if they want to re-locate to the more comfortable seat, especially on a long flight.

Great flight, no bumps to speak of, pleasant crew, good inflight entertainment choices

I am always uncomfortable about the boarding process. I think every airlines has their own procedures for boarding but all of their procedures are inconvenient because it takes too much time to board. If you board people from back seat to front, I think you can reduce the time to boarding.
