Quick and easy check-in. Love how technology has helped speed up the flying process. Smooth flight to a Seattle and back. 10/10

Ok. It was uneventful and drama free. Plane was clean and the crew polite.

The plane was late taking off. We sat on the plane at least 45-60 minutes before moving away from the gate. Im 5’9” and 185lbs and there is no room in those seats. On top of that you shoehorn a waterbuffalo of a woman in the middle seat to where her sweaty rolls and arms were well into my seat and touching me the whole time. It was either that or press against the opposite arm rest and get hit by the beverage cart and every single person who walked by.

In GEG I arrived at 0930 for a 1600 flight. Alaska had a rule that you could not check your bags until 4 hours before flight time. I was forced to sit in a chilly lobby for hours. I had access to a bathroom, but could not go into terminal for food and drink. Boarding and flight OK

OK for the price paid but nothing as far as value.

Way too warm for that length of flight!! If the pretzel bag gets any smaller, there won't even be any pretzels to eat!! Crew didn't talk. $99 just for an aisle seat is ludicrous!! Probably won't fly Alaska again.

Had to go in the bus to board the flight. Was traveling with just a carry on, but Carry on luggage was recommended to be checked in and it took a while to come to the baggage claim.

No problems at all. Thanks for the safe trip. Henry

Flight was on time, inflight service was professional and attendants were so pleasant.

Very Large person sitting next to me and taking up a lot of space including mine

I am still upset that my bag was lost on a recent trip to Rome ; we were inconvenienced and out €150 Euros ; delta has refused to reimburse us

I am very bothered by the events today. I can't believe the flight attendants allowed someone to take my seat and made me move. It was embarrassing. I was in the right. The lady just didn't want move. I can't believe delta would allow this to stand and disrespect my rights as a passenger. The lady complained about her leg and that she couldn't move. Firstly somehow she was able to make it to row 24. Not sure how much her leg could have hurt. Secondly, I'm in plenty of pain myself. I just finished chemotherapy a several weeks ago. My body is constantly sore. Yet deltas flight attendants didn't appropriately protect my rights. In the end they found me a seat on the plane but I want to understand how delta can operate this way. They in essence allowed a bully to get their way.

Good flights. On time. They had a gluten free snack option which was nice

Take this flight once or twice a month. Just don’t cut it from the schedule.

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

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

Flight was delayed due to weather. Crew did a nice job of making us comfortable. No complain complaints.

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

Delta flight was on time, seats were comfortable, and crew was nice.
