I needed to board early and that was no problem. The snack was just ok. Alaska is an EXCELLENT airlines . . . luggage fast and easy.

Alaska Airlines needs more bag tag kiosks and bag check-in stations in Seattle. A single entry point for the bag tag kiosks would be helpful. This alleviates lines forming at each individual kiosk, which causes traffic jams for people passing through.

It was raining and cold and we had to walk outside to board the plane. And to have yo stand outside to wait in line to board. It seems they could find another way to send a few people at a time so passengers are not outside in the elements. Then to not have my luggage show up at my finally destination. Not happy with the whole experience.

I paid $49 to select my seat---6A a window seat just behind first class. When I started to get on the plane I was told that my seat had been given to someone else and I now had a middle seat. They finally gave me an aisle seat. When I told them I wanted my $49 back, I was told I would need to call alaska and fight with them to get my money back. And when i was on the flight people going by kept hitting me with their bags. I have tried calling alaska twice to talk about a refund but never got thru to the right person!

Check-in was easy, I did it from the app. Boarding was easy, the crew was great. Santa Barbara airport had a disabled plane so we had to land in Burbank to refuel. They kept us well informed, and everyone was great. A very entertaining person from the Burbank airport got on and told a few jokes.

It went very quickly even though we were late in leaving Fresno.

Like I said before the internet was shut off so there was little to do on this leg of the flight.

Finally get a snack n drinks! Just like the good ole days!

SeaTac was a mess first class check-in not clearly identified Temporary signage needed since only one door into Alaska check-in area directed you to coach baggage check.

We could not find a parking spot in the garage so we left airport to find a parking lot. We were late and afraid we would miss our flight. We were greeted at the new Alaska check in and I was really upset. She got two people to put us in wheelchairs and we flew through the airport and security. Then all the way to the N gate and on to the plane. Somehow they hadn’t taken off. These two individuals deserve a medal for getting us to our flight and onto the plane. It all started with the wonderful greeter at check in. I wish we’d gotten her name and the two who got us there.

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

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.

Boarding always seems a bit chaotic. Seat spacing could leave more for leg room.

Good flight. On time. Boarding and seating was easy. Crew were really friendly, yet professional. Bathroom (by cockpit) was small but serviceable. Some the seats were showing some notable wear & tear, but were comfy. Very happy UA customer. TY! 🤛🏽💗

We arrived early and finally made it to our gate almost an hour after.

We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again

Everything good until we waited for jet bridge at SFO. Then pilot gets on speaker & said it won’t reach plane- too short, need to go to different gate. Then 5 min later, adjusted plane/jetbridge & all ok?!?

Was a pain having to leave the plane and reboard but glad the plane was fixed
