The crew the employees were friendly and excellent. There was a problem with the plane and they had workers there immediately working on it. They made sure the people that had immediate connects knew what gates they had to get to and had them leave the plane first. Very thoughtful.

We waited over an hour for our luggage to arrive at the carousel in Seattle.

Like the friendliness of the crew, each flight had a very very drunk person next to me and the last flight had a very obese man pushing me into the aisle while the crew kept ending up hitting me in the shoulder with the beverage carts.

Flight was about 30 minutes delayed. All staff were friendly and professional while keeping us updated.

My screen was hard to change channels….seemed it was worn out….i just gave up and read a book I brought

Booked a first class ticket from Anchorage to Seattle but was denied complimentary access to Alaska Lounge as our 1500 mile flight wasn’t long enough’

We were lucky to be seated in an upgraded row and received free drinks!!

Everyone was very helpful. My only critique was the very hard landing in Seattle. We felt the G force.

It was absolutely terrible due to the mother and her two children sitting across from us. The 2.5 year old jumped up and down on the tray table. Every time the kid screamed the mom would grab the kid and scream even louder into his face. Horrible flight. The mother stayed on her phone playing while the kids were so destructive to others hanging over seats, she never once tried to comfort or discipline them. She never once said you cannot jump on tray table. Definitely the worst flight ever. It was my first time with Alaska Airlines.

It was great. There was legroom. The food I ordered was creative and flavorful. The crew was kind and fun. Definitely would fly with them again.

Food from the flight from Atlanta to Santiago was very poor..

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

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.

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.

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.

Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!
