Now that Spirit is not around Alaska took over the title of cheap and worse airlines with high prices for garbage cheap planes. Seats recline the entire 2”. What’s the purpose? Just make the stationary. Crew is on steroids. Food is like McDonald’s happy meal. Only happy in the name rest is garbage

The flight was delayed out of BIL so many times that I was not able to make my connection. I was rebooked for the next day, losing a full day of my trip. I still have not been compensated as promised.

The flight attendant and first class were very friendly, efficient, and wanted to make sure that service was great. Highly recommend this airline.

Comfortable seats, good drinks with lots of water refills, staff was kind and understanding of my disabled mother!

Easy check-in. Good customer service. Had to check carry-on due to lack of overhead space. Wish the airplane was configured with more overhead area so this doesn't usually happen.

I liked that the crew was friendly, we left and arrived at near scheduled times, plenty of on-board crew to handle the cabin service for the flight and I found the price of my airline ticket to be excellent!

Had no way to see what gate came in on or what gate connecting flight would take off.

Planes were on time. Pilot kept everyone updated. Crew was friendly and helpful

I have mobility problems and requested wheelchair assistance in Seattle and Anchorage and none was provided at all. Very disappointed. Only one gate agent in Seattle asked if I needed assistance boarding my flight in Seattle.... and only after three gate changes.... requiring even more extremely painful walking without assistance.

My travels went as smooth as they probably could have, I expected delays upon delays but to my surprise even with the small delays I had I was still able to make all my flights. Thanks -Josh

Seats were not bad enough and uncomfortable good legroom in the emergency exit row we were in, but we were forbidden to hold my grandson on my lap for a little while, and the stewardess passed us saying it was against regulations which makes little or no sense when you’re 36,000 feet. The food snacks were really bad. Tasteless tasted like wallpaper, but we’re supposed to be protein bars, and the announcements were all completely incoherent because of the noise of the airplane and the lowness and crackly nature of the PA system.. this was disgraceful. No one in our party could understand a word of what the captain or the flight attendant were saying —not a word! The landing was a little hairy in a pretty stiff crosswind -we bounced before the plane stabilized on the runway

Crew was nice, meal was good. Entertainment had to be rebooted 3 times and still did not work. Turns out there was residue on screen, it needed to be cleaned to prevent the touchscreen buttons from continuously activating. I had entertainment for the last 45 minutes of a 5 hour 45 minute flight. Really unacceptable for first class. Flight attendent indicated your cleaning solution creates this problem. Seems as if this is widely known, you should be using a different product or cleaning better. Really really disappointing which simply added to the wi fi on your planes with reliably never ever works.

Long flight but comfortable and not freezing as I have experienced on Hawaiian flights to the islands. They gave us blankets just in case. Nice touch.

NEVER MADE THE FLIGHT BECAUSE DELTA SAID THEY CAN NOT

Everything I mentioned earlier - the airbus was more comfortable indeed and the experience was further enhanced.

First class and monitors weren’t working for mine & my husbands. Eventually fixed, but quite annoyed as we bought first class. Also, No foot rests.

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Didn’t make the flight. My connecting flight was an hour late and I missed the flight. You rerouted me thru Atlanta and I arrived in Rome over 10 hour after my original Rome arrival time. You also left my luggage in Atlanta and it took you three day to get my bag to meI spent 4 days in the same cloths, I had packed my prescriptions in the lost bag and went 3 days withoutMy heart meds.

Great staff. Clean plane, but we were delayed for more than an hour due to maintenance issues and had to board another plane.

Overall a good experience, but no wifi available for free or for purchase and we got wet from condensation or other water source during descent.

I’m so sorry, I can’t remember her name, I believe it was Dimpti. She was stellar, also a mature Asian flight attendant, lots of flowers in her hair, just as amazing! But literally the crew was AWESOME . Only downside is there weren’t any charging outlets. Maybe I needed to ask a flight attendant , but it would’ve been nice to have one easily accessible.

Older aircraft, no meal, only food was for purchase. Not impressed United.

Stuck on tarmac for two hours plus a 5.5 hour flight. Rude flight attendant. And no meals, not even for purchase!

I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.

Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.

The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.
