WOuld have liked coffee or pretzels but other than that, crew and pilot and flight were great. Seat was great, too.

The flight 2161 was cancelled after repeated delays; for some reason the crew and not the tower located in Billings, Montana made the call. A cancelled flight is not a big deal, it happens. It was very disappointing that upon cancelling the flight it was a free for all to get to the counter for rebooking. Priority seating and first class ticket holders should have been giving priority to get on the next available flight. Most would agree that the process of moving states away, w/a cat, is stressful. A cancelled flight, 90 minutes to rebook, no place to stay, medication that was to be refrigerated and trying to find a local pet friendly hotel significantly added to the stress. Had I been able to rebook (per priority boarding SOP) I could have called the place I had just checked out of as my room most likely was just as I'd left it, including with pet supplies (which also had to be repurchased). While waiting to rebook, many of us called Alaska Airlines 800 number hoping to get a new flight; the waiting time -- this is not a joke -- was eight (8) hours, which dropped to "just" two (2) hours about 45-minutes later. Due to the cancellation I had to spend $268.75 and I still have not been refunded for the change in ticket (first class to regular). Each time I've call, five times now, the wait time was absurd, or a message of call back is given. Hopefully visiting the airport and talking with an agent face to face will be the final chapter to this experience. Alaska has been my go to air travel for years, hopefully this trip was just a hiccup. A system that forces customer's to spend hours of their time (money) to get a just due refund is not a working system. I suggest Alaska Airlines hire more representatives to handle calls; time is more valuable than money, spending 90 minutes to rebook a flight, without the difference being automatic is absurd. There are things called computers, they do amazing things. Once the flight was cancelled, only three agents were working to rebook the PAX, This too was unacceptable. First class ticket holders pay for first-class service, this should include rebooking on flights that are cancelled. I recall a time when flights were cancelled the airline would offer a hotel should the next flight not be until the following day? I had no idea that was no longer SOP; many could return home, several of us could not. The agents were pleasant once the PAX had their turn to rebook, this was true down in baggage area as well. The flight out the next day was also what I'd come to find of Alaska Airlines.

The crew inside the airport for Alaska was rude, lazy and incompetent

Generally very good. Waiting (due to de-icing and traffic) in plane to take off was a put-off. But it's not the airline's fault. I find Airbus more comfortable than Boeing.

Smooth flight, on time despite Captain’s forecast of troublesome weather conditions.

The flight was a disaster. It is a 40 min flight and we waited to the tarmac for well over 90 min with no updates, while the crew tried to reconcile the seating chart of people on the plane to what their phones showed. Terrible communication, systems and experience. I would do almost anything to avoid taking another Alaska flight after the experience last night.

Larger seats with a bit more room would be good! Thanks for all your hard work. I think we are all feeling a bit down these days economically and your positive attitudes, both from SJC to Seattle and from Seattle to Bozeman makes more of a difference than you can see! Thank you and Merry Christmas! I hope all your financial needs are met and that very good things come your way.

Food was bad. Just a drink for a 5 hour flight

Leg and arm room are horrible. I am not a big person and found it tight.

I purchased a 1st class ticket and unfortunately the main flight attendant was not the best and seemed more interested in her phone than the passengers at times. Then the plane didn’t get restocked and the only snacks for this flight were pretzels. However I would like to say that the rest of the flight crew and ground crew at the airport we’re great, especially the people that wheeled me around the airport some and then the one getting me to the plane and the automated wheelchair that wheeled me through the airport.

Very old plane with no inflight entertainment. I purchased the internet pass and it was nearly unusable.

My tray was broken so i had no place to work or eat except my lap. Flight attendant said I would get an email with some credit or miles, it was a complete waste of time as I could only function at about 20% of normal. I have not received anything yet.

Short trip, no food and therefore no expectation for much interaction with staff who were pleasant and professional. My critique is on comfort of the seats. Exit rows and comfort seats do not provide enough personal space for 3 side-by-side seats, especially when in the middle row. Some passengers are not considerate of the middle seat and there should be signs that state something to the effect of: "please consider giving middle seats use of the armrests."

My flight yesterday evening was delayed 3.5 hours with no water or food service. Poor experience

Transparency from pilots, quick boarding and exiting the plane, staff greeted to each and everyone,

Didn't like sitting on the waiting pad for 30 minutes right after departing the gate. If you're going to do that, just don't board so people can still get up and walk around in the terminal. My luggage was damaged by the baggage handlers.

Pilots lied about waiting on “paperwork”. Sat in the plane for over an hour, waiting on some papers to be printed according to the pilot and then all of a sudden he says good news maintenance is finally on their way. Maybe they can fix it before we get our paperwork. Ended up missing my connection in LaGuardia and as a result, had a fly home to Lexington instead of the Louisville airport. Then paid $100 to uber to Louisville since it was midnight by the time I got in. I wish they would just be transparent with passengers sometimes and not try to beat around the bush on why things are delayed.

The WiFi was horrific. I fly delta often and love their (usually reliable and free) WiFi. On this flight it was intermittent and when it did connect was extremely slow. I couldn’t get any work done while I was on the flight which was extremely frustrating. I was also in the exit row seat where there is now immediate seat in front of you, so while the leg room was nice, I couldn’t even watch the TV when the internet wasn’t working. Finally, for the last 20 mins of the flight, the announcement indicator came on the TV screens and took them over, even though no announcement was being made. Really disappointed.

The flight was way too HOT! And the plane did not have any in-flight TV entertainment.

The tray table was broken and the food was terrible.

My bags were misplaced!!! Im in a foreign country with no bags

The entertainment options on the seat back video boards were nice.

The flight I was supposed to be on was supposed to take off at 1:50 from State College. It was delayed over and over and over again until somehow I had to rebook on a flight that was supposed to have left State College at 8 am that morning but didn't end up taking off until almost 6 pm. Not only was this completely unacceptable, the "token from United" was a 15 dollar meal voucher that has to be used by today. I would personally like some miles added to my account for this inconvenience. I was in transit for 8 hours from the time I arrive at State College Aiport to when I got home. I was supposed to be home at 3 pm and I returned at 8 pm. Unacceptable. I have not been on an on Time united flight in nearly 5 years.

Crew was friendly. Seats are too narrow, particularly when a big person is in the adjacent seat, but I understand this is due to smaller planes usually flight into Lincoln. I have experienced several flight delays going out and coming into Lincoln airport, I say maybe 50% or higher of the flights I've taken out of this airport have been delayed.

newer aircraft, ability to connect my headset via blue tooth for entertainment.

Great flight. Boarded efficiently. Arrived early at CLT. There was no in flight entertainment on this aircraft. Great crew.

The seat was comfortable. There was a lot of turbulence. If it weren't for that,it would have been okay.

It was a red-eye, but the flight felt surprisingly quick. The seats were very comfortable, and that made resting much easier. I also want to thank the gentleman seated next to me, who graciously moved so my mom could sit beside me. We slept almost the entire way. The cabin crew was respectful in not disturbing us, while also being courteous and professional throughout. Thank you, United.

Packed in plane small uncomfortable seats elbow to elbow nobody wants to be in that situation for the money they paid

Overall flight was ok. Flight attendant was receptive to assisting passengers with tight connections.

Jet Blue has excellent everything, Friendly customer service and staff, clean aircraft’s and is always on time.

Entertainment and wifi were very sub-par - audio issues and no wifi

We were delayed and had to circle due to weather and had to divert for fuel. While I understand that you can’t control the weather I would have appreciated knowing that the crew wasn’t going to run out of hours and then having to spend the night in the Raleigh airport.

Messy plane that was falling apart Small screens that didn't work

I was traveling with two small kids and our TV s were the only ones not working. Informed the flight attendant who did nothing about them.

They forced me to check my hand luggage at the gate.

I specifically choose not to check bags to ensure I can proceed directly to ground transportation upon arrival. However, due to a recurring lack of cabin space, I was again forced to gate-check my rolling luggage after going through my luggage to take out electronics and batteries. This practice unilaterally changes the service agreement made at the time of purchase. JetBlue needs to find a better way to manage overhead space that honors the carry-on baggage allowance.

Still hasn’t left. Why are you asking how it was?

Flight was good wish there were more snacks options for such a long flight but stewardesses were very pleasant as was flight crew.

I was denied a plastic fork to eat my food and was told plastic forks are for paying customers who buy Jet Blue’s food. So I had to make a utensil out of a cup so nourish my body. Like a refugee. Because decency is dead.

Flights on time w/o delays. However, my baggage was damaged. Ground crew, throws baggage from plane to the baggage carrier, carelessly.

This short sector between Miami and JFK was undertaken purely for business purposes, with efficiency as the primary objective rather than a full inflight experience. Overall, the journey met its intended purpose; however, the ground experience at Miami stood out significantly. During check-in, I was unable to link my frequent flyer details from Qatar Airways (oneworld alliance) through either the self-service kiosk or web check-in. The situation was handled exceptionally well by the check-in agent, who demonstrated remarkable ownership. She coordinated across multiple counters, ensured my frequent flyer number was correctly reflected, reissued the boarding pass, and confirmed that mileage accrual would be recognized. Additionally, she ensured the boarding pass reflected priority status, enabling a seamless priority check-in experience without delays. This level of proactive service was both commendable and impactful. Boarding and the inflight experience, operated by American Airlines under a codeshare arrangement, were efficient but largely transactional. While operational delivery was smooth, there was no visible recognition of oneworld frequent flyer status onboard. In comparison to the consistently personalized engagement typically experienced with Qatar Airways, this absence was noticeable—though understandably a potential limitation of codeshare alignment rather than a direct service shortfall. In summary, while the flight itself fulfilled its operational intent, the exceptional professionalism and commitment demonstrated at the Miami check-in counter was the defining highlight of this journey. Greater consistency in elite recognition across partner airlines would further enhance the overall experience.

I was able to get the AA customer Service desk to put me on an earlier flight without any issues.

The seat was comfortable, the attendants were very nice and WiFi made my life so much easier with work. Kudos!

Flight was 3 hours delayed. They gave our plan to two other routes. Need to knock that off.

To have arrived on time and not 3 hours late after having already spent $100 to change to an earlier flight, only to arrive back home close to the original flight time.

No gate in Rome. Had stairs. Got separated from my wife in a wheel chair. Customs was a zoo. If AA doesnt have landing rights, it should be advertised.

I almost missed my flight and they helped me out enormously

Business class was very good, one of my best flights

The "on the ground" A/C was not working. It was so hot while waiting to get in the air, a passenger from the rear of the plan declared "I just can't!" and waited in the gangway until time to close the doors. It was miserable. But the crew were champs and had an amazing attitude. I know they were as miserable as we were but didn't let that affect their performance.
