Great crew, smooth flight and landing. Wish they would offer Dr. Pepper and a choice of flavors of pretzels.

Thank you still providing bags for vomit. My son had a migraine and needed a bag to vomit in and it was right there behind the seat in front of us. Thank you!
Flight was great. Boarding was crazy because another flight was boarding late next to ours so everyone was standing and in the way.
All good! No entertainment on this new plane yet but ok for this short flight. Great on time flight! Thanks
These questions are hard to answer. It was not until I checked in that I learned my flight was going to Seattle for a connection and not Portland. I did not get notified, or asked, about this change by Alaska or Kayak. Thankfully I made this flight; but missed the connecting flight and it took me much longer to get home. A service representative for Alaska says this happens frequently with third party companies, like Kayak. Please please figure that out.
I got the last seat on the plane, in the back in the corner against the window, and I paid a competitive price for my ticket several weeks before the flight.
Personal demeanor not good on flight returning to LAX..Great and superb on the way to Portland
Quick boarding, efficient and pleasant crew. Wish they worked the mic better in the terminal to be understood more clearly.
Flight was cancelled while everyond was on the plane, ready for take off
Boarding, crew, and duration were great. The lack of built-in entertainment is a turn-off, especially in this day and age. I’m also tall, so comfort is always an issue. More legroom without extra cost for taller passengers would be great.
Both flights were late 2+ hours with ZERO communication from the airlines or their staff. No offers for compensation. WiFi didn’t work for streaming and they said to only use browsing but that didn’t work either. Waste of $$. No drinks only boxed water or apple juice. No snack. One of the worst flight experiences I’ve ever had.
This was actually an Alaska flight. I was not able to check in online using the Kayak app or the web for Hawaiian or Alaska airlines. So I contacted Hawaiian and they advised that I had to go to the counter when I arrive at the airport. So I waited in line at the Hawaiian counter for 45 minutes. When I got to the ticket agent she advised that I needed to go to the Alaskan Airlines ticket counter. So I went to that counter which thankfully was not busy. I received my boarding pass and then went to security. I arrived at the gate as boarding was beginning. The frustration is that Hawaiian or Kayak should have directed me to the correct ticket counter. When it is “operated by” a average person doesn't know what that means. Kayak app was silent on what action to take when I was unable to check in online and Hawaiian just stated my ticket number and confirmation numbers were invalid. Communication is key and this process could be cleaned up. Thank goodness I am savvy and speak English, I can’t imagine this process for someone who may not be.
Flight was canceled with no voucher of any kind and next available flight was two days later.
It was very pleasant. The staff and crew are very polite.
On time. Alaska upgraded seat comfort with memory foam seat covers with head rests
There were several delays and we were stressed about making our connection. The announcements for boarding were hard to hear or understand. The seating was uncomfortable for a 6 hour flight.
When I was not allowed by Alaska airlines to board due to time and difficulty pre-check the night before and kiosk did not work when I arrived at the airport and then finally told Alaska airlines is where I had to go. Not Hawaiian airlines that they had moved. That's when I was treated with the utmost disrespect by Alaska airlines agent that I was not allowed to board. And that might ticket to return was canceled and I hadn't even left yet when they gave me the option for the next flight to raise my flight price to $300 one way. I bought a $96 round trip ticket and they're trying to gouge me for $600 in addition and canceling my return flight.
Despite two calls as well as a chat on the website, Alaska would not add my TSA number to my reservation. The flight was switched from Hawaiian to Alaska which caused them to mess this up in the first place
The departure gate was changed from C1 to B18 but it was never announced at the C1 gate nor did I receive any email or text message or phone call about the gate change. I was in a window seat. In the other two seats next to me were Mr. Rotund and Ms. Rotunda, a youngish couple. Just the two of them should have booked three seats. I was smashed up against the wall and window for five hours. Overall, I'd say my flight sucked. Wouldn't you?
I couldn't get checked in 24 hours before either leg of my flight. I tried both my Alaska and Hawaiian codes on both apps.
Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.
Flight was late as pilot crew had to land at different airport in their previous flight. Passengers boarded and had to wait for pilots inside plane. Series of incomplete and unnecessary announcements by an annoying voice, rather than complete, informative announcements.
Breakfast was not loaded at SFO due to catering company change. Seems like a major airline at a major hub would have thought of something else or warned passengers to pick up food before boarding a 3 hour flight.
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.
They hired a new catering company the same day of my flight. They botched the job by not delivering the right carts and after THREE HOURS waiting, the flight crew timed out (flight was 19 hours long and FAA rules state crew can’t work more than 14 hours long). So they CANCELED OUR FLIGHT!! Worst experience ever. Avoid UAL at all costs.
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.
While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.
get E+, a must for 5 hours flight if you are tall
Compared with other carriers business class for an overnight was not worth the extra expense.
Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)
The chair cushions may need an upgrade. I have been noticing they are so worn out, thin so you’d sit in a dip 😄. Other than that, all was an enjoyable trip. Thanks AA!
Cramped seats. FAA should make airlines have more legroom, for even short people complain
Eventless. It was a good flight and good crew. Can’t complaint.
Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.
British Airways staff are very polite and willing to help.
The plane was late and then sat on the runway for almost 45 minutes before taking off.
We kept being told that the flight was full and that all overhead compartments were full and therefore had to check in our hand luggage. We were some of the last people to board and noticed that there was still sufficient space in the overhead compartments. We were obliged to check in hand luggage when there was space and so had to wait at luggage retrieval which took a while to then noticed damage to our luggage - not a great experience!
This was an overnight flight. There was no meal service in first class, just a simple snack basket was offered along with beverages. There should have been some type of continental breakfast prior to arrival in PHL. As an Executive Platinum American Airlines Advantage member, I received no name recognition from the first class flight attendant. When disembarking at PHL, the flight attendants were more interested in their cell phones than saying "thank you" to the passengers as they disembarked.
The flight was quick and to the point. The crew just did their job w/o excessive talking and everything was just perfect.
Awkward carry on process. Forced to check all carry on. No overhead space of worthiness. Left delayed, but made up the time. Crew was amicable.
Cancelled flight after I arrived at airport after 75 min drive and parking. Next flight was 4 days in the future. Had to scramble and buy a much more expensive flight on another carrier.
I liked the turn-style feature at gate 209B at LAX. Very efficient process. The gate staff also made several, clearly directed announcements so I felt very informed.
The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.
It was a short flight so no food or entertainment….
The worst flight of my life. Never will I fly frontier again
Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.
Flight was delayed 3 times, would have been nice to have received text message instead of email notifications. Frontier app wasn’t even updated accordingly, no gate number disclosed. No agent at front desk of gate to inform of delay. Very confused and left if the dark
They changed the timing , first delayed by 4 hours then went back to 40 mins late, we had to run back to airport to not miss our flight. This is ridiculous
No frills for sure. No gate announcements about flight delay, not even water to drink on the flight.
I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.
