1.5 hour delay boarding plus 1+ hour sitting in plane waiting for ground crew to load luggage and freight, made for 3:00AM arrival in Seattle.

1.5 hour delay boarding plus 1+ hour sitting in plane waiting for ground crew to load luggage and freight, made for 3:00AM arrival in Seattle.

The second leg of my trip left without me despite being my inbound transfer only a few minutes late. My friends told the gate agent and they closed the doors and left early anyway. Then they tried to rebook me on a flight SIX hours later which only changed when I got a supervisor to make it 4 hours later. The gate agent was nasty, unhelpful, and walked away from me.

Worst part is being squashed in a seat ( I am not fat) and unable To get comfortable

Took forever to get on board. Flights was one hour late.

They always change the schedule. My original flight got canceled. They put me up in the air flight. I had to stay seven hours in Seattle. That is bad.

I had a great travel experience with Alaska. The agents and cabin crew were all so pleasant and helpful. The plane was clean and comfortable. The connecting flights went smoothly even with some minor delays. All in all, it was nice not to be upset with the journey. I say that because over the last few years all my travel has been on Delta and American, and always involved cranky employees and flight issues. I wish Alaska flew everywhere I need to go. Will definitely fly Alaska every time I have a choice. Thanks for helping me look forward to traveling again.

Disappointed that there were no TV screens to watch a movie on the six hour flight. Disappointed that the plane did not have the right adapter to connect my phone and my iPad and charge them.

Ted. F/A in fist class did a great job! Very nice

It was a short flight so no refreshments or entertainment which was fine.

The plane was freezing and no blanquets available unless you buy them. My screen was bad so I couldn’t watch any entertainment.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

Terrible and im avoiding them in the future. My initial flight was delayed causing me to rebook my flight and when speaking with the representative to rebook I explained this is the second time my flights were delayed and they did nothing to help me. I wasn't booked to comfort plus or given a voucher or anything. I was almost late for my meeting that I needed to attend on Monday because of the games delta played delaying my flights even more and putting me in the very back of the plane next to an extremely intoxicated passenger

Flights on time. .Ride was as comfortable as can be expected in steerage. Luggage arrived at destination. Attendants were fairly friendly.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

The WiFi didn't seem as fast as it normally is

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

The crew was wonderful and attentive. The seats near exit row were restrictive. Offer healthy snacks please

Flight left early and arrived early. the whole trip was excellent.
