The flight itself was okay, but there were 2 screaming kids in front of me my entire flight which made it just awful. The parent did zero to try and make the children settle down and flight attendants did nothing either. I understand it's hard to travel with children, but constantly yelling, screaming, or loud talking for 4 hours straight is just ridiculous.

There was an issue with water that led to us not having potable water onboard. They dumped the onboard water and we were two hours late taking off.

All good. Great food and entertainment when there isn’t any on a one hour flight

Boarding for Alaska Airlines is always chaotic with many people crowding the gates. Arriving in on Alaska in Los Angeles is always interesting since there is never a gate available. So the planes are often parked all the way out on the west side of the airport while waiting for the gate to be cleared of the departing plane. This flight was no exception.

Flight was delayed about 45 min and they never offered an explanation. Peruse, staff were friendly and competent and the flight was safe.

It was a really smooth flight. I hate heights. All made it feel smooth. Thankyou

No TSA pre check on boarding passes. Was told known traveler numbers are only kept with Alaska Airlines mileage plan members. Did not notice until reached the head of line, and then was sent back through the line to general boarding which took almost an hour. Learned two things: check our boarding passes, which we haven’t had to do with our other airlines, and don’t fly Alaska! You used to be much better!

I wouldn’t fly with Alaska again if you paid me.

I’m still waiting on my luggage. They canceled my flight on valentines day and my girlfriend broke up with me. Alaska airlines literally ruined my life.

Flight was delayed twice, I was forced to check my bag, and the only offered water or apple juice on the flight

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️

This was the second flight this week with flight attendant Marcus I’m not sure if his last name is Lane or Lang but this guy is awesome. He funny, attentive and his service is 5 stars. Marcus makes business travel more enjoyable !

Although the flight left late, we arrived early. It was one of the quickest boarding and off boarding experiences I’ve had. It was kind of annoying the only drinks they had were water, coffee, and tea. The flight was very smooth, temperature was just right, and flight attendants were friendly.

Lower number on this flight so spaced out passengers. Able to enjoy more room to relax during flight. It was lovely.

Kind staff. Snacks are small but that’s the new normal.

The young man who was our flight attendant in first class was lazy and did not do his job well at all. Never offered drinks upon boarding - actually I take that back... said "are you okay with water" as if I do not want to get you anything else, only passed the snacks around once, got my drink order wrong and then never offered a second round of drinks. He was the worst I have ever seen on Delta and we fly a lot.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Flight left early and arrived early. the whole trip was excellent.

Seats were really tight and the seat belts did not give enough slack.

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

The tv monitor in front of my seat was not responding. The flight crew reset it and it still didn’t work.

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

Terrible. First of all we were delayed 4 3/4 hours departing Honolulu. As we had to leave our condo and the rental car had to be returned we had to go to the airport. Even though we had a business class boarding pass to Washington, since we did not have business class to Montreal we could not access the lounge without paying a $59 fee each. This does not make sense to us. Since we could not meet our original connection United booked us to Montreal via New York LaGuardia on Air Canada. In Washington a further delay got us into LaGuardia too late to make our connection to Montreal so we were booked on another Air Canada flight 3 hours later. We were originally scheduled to arrive in Montreal at 10:40 and arrived at 19:55. A totally exhausting day, United did not offer a meal voucher or any type of compensation. Air Canada did give us a digital meal voucher. The food in United business class is poor among all meals offered. The pods look nice but are not that confortable. Overall would not fly on United again.

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

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.

Our seats were all the way in back of the plane,

Food choices were very limited. Taste of the dishes was average.

Maybe add a seat trade app for flyers that didn’t get seats together
