It was a good experience! Thank you:) No sparkling mineral water… 🥲

On time, WiFi worked, reasonable legroom, helpful staff. Unfortunately there was no water for handwashing in the rear lavatory.

Miss bigger screens for movies Staff was friendly Seats comfortable Bathroom line long

Seats are so small now that it's very hard even for a medium-sized person to be comfortable!!!

My experience would’ve been great because we were on a new plane, but they said as we boarded that the plane would be too new to have WiFi, which to me is unreasonable - newer planes should def have WiFi! It was a 5 hour flight from Anchorage to San Fran and because there was no WiFi, I had to take an unexpected half day off work, which was super annoying because I had a lot to do and we only found out a few minutes before takeoff.

I liked the crew. There was no food flight to short

2 FLIGHT DELAYS? what an inconvenience to stay @the airport HALF THE DAY😳from 1pm till boarding @ 4pm pass 😠exhausting !

Flight was delayed - we left at 11:30 pm instead of 10:30 and it was extremely inconvenient. It affected both the day of the flight and the next day

I don’t like it stuff not friendly and no one help for my mom she 82 years old lady I requested wheel chair but no one provided and no one help.

If there were movies it would have made the flight much easier.

First class ticket. They ran out of food and I sat hungry watching the others eat

Agents talk too fast over intercom. I know it’s memorized and we’ve all heard it before. Just slow down a little. Stop charging for checked bags. I was pleased to get my bags promptly at each end of my flight.

Everything was great except having to check in at Alaska. That was a surprise and took extra time and effort. Should have been explained somewhere maybe on the HA electronic ticket.

I accidentally made this purchase and they wouldn’t refund me even though I called immediately to cancel it.

You. Changed my AIRLINE, CONFIRMATION CODE, TERMINAL. AND GATE COMM N CATION. WAS POOR AND SUBOPTITMUM AND RIDICULOUS MY AIRLINE WAS HAWAIIN. ,THEN SUDDENLY. YOU SAY IT WAS ALASKA Give me a break,,Black is not White I could not check in over the phone...all I received was Error. And info from Hawaiian air agent saying tooooo many people were trying to check in causing the problem On the other hand I am alive

I like that you have eliminated plastic cups, bottles and straws. The crew was conscientious about separating the used paper cups from the trash. This change to paper is a great move and makes me want to choose Alaska when I fly.

Attendants seemed un-engaged and indifferent when asked for assistance.

Overall it was a good flight. The thing I most appreciated was that you eliminated plastic cups and water bottles and stir sticks and had paper cups, wood stir sticks and cans. Plus, I saw that the airline staff were actually keeping the used paper cups separate and unfolding the used cardboard meal boxes and keeping those items separate from the trash. Good for them! This makes me want to support Alaska Airlines and fly Alaska again. Thank for taking this step in working to reduce single use plastics! Kudos!

Ok but why they need to sell the ear buds?

Your Hawaiian airlines record locator number did not work! I could not check in in advance at either Hawaiian or Alaska airlines website and had to wait on long lines to check in at the airport. This caused considerable stress and I was worried I would miss the flight and thus had to arrive even earlier than otherwise. Finally, I wanted to change my flight and could not do so because no record locator was recognized for me to make changes. This was a very poor experience. Also, I could not go in and check or change my seat assignments. I was assigned a window seat, which is my least preferred location, and which I have not flown in for years. Please advise as to what kind of customer service gesture you can provide to make up for this below par experience.

1. when we went to check in, our 2 first class seats had been CANCELED and the flight was sold out. This was done without our prior knowledge. It was all we could do to restore one first class seat for my wife and I flew economy. 2, Our flight home was scheduled to leave at 10:30 pm. Due to tsunami warnings, the roads were closed and our flight status was uncertain as to whether it would leave as scheduled. It was announced that it would now leave at 11:20 pm and the roads were now open since the tsunami had come and gone. We made a mad dash to the airport and checked in. Delays were announced at 12:30 pm, 1:30 am, 2:30 am and at 3:30 am it was canceled. Since this was a flight due to natural (tsunami) causes, there was no compensation. We were told to return at 1:00 pm the next day and our baggage would be kept on the plane since the same plane was going to leave at 1:00 pm. We had to return to our hotel for the rest of the night. The same plane did not leave at 1:00 pm and our baggage was gone! All in all, it was a miserable performance by UA. Information was hard to obtain and no one knew what was going on and what was going to happen. Hundreds of passengers slept on the floor, chairs, etc. No food and no water was made available to the passengers. It was a situation where UA could care less what was going on. As a one million mile flyer, I had not experienced anything like this before and it was hugely disappointing!

Boarded plane and then delayed 1.5 hours while on the plane

My flight was delayed a very short period of time but they did not hold my connecting flight to San Diego, also through United. So they closed the doors before we got off our plane. They would only have to help the door open for another five to ten minutes. So I missed a court deadline for a manditory mediation settlement conference for my client. I had to get an associate to be there in person and be on the phone with him relaying what he needs to do the entire time. The court was very upset with me and so was my client. United cannot be trusted.

Really good 😊 the woman at the gate entrance was a little rude checking in our carry-on but i dont think she worked for the airline, she worked for the airport at sacramento, other than that amazing.

Boarding was mayhem. Late boarding by 15 minutes because of lack of staff (missing 1 flight attendant. We had to wait for an arrival of another plane before we could board). Flight was a little rough, but cannot blame on airlines.

United out of SFO is having issues with catering so none of our meals were loaded on the plane and no offer of compensation for our tickets purchased was offered.

A bit rush for transit. Food and entertainment are not available

The gate was too far away for the connecting flight

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me
