Flight was delayed 2 hours. It was too cold inside the cabin. My seat mate had no jacket so she was shivering the entire flight. The stewardess says there’s no available blanket.

Flight was delayed 2 hours. It was too cold inside the cabin. My seat mate had no jacket so she was shivering the entire flight. The stewardess says there’s no available blanket.

The plane had to sit on the tarmac for 45 minutes once it had landed. Not Alaska’s fault.

Flight was cancelled just before we boarded. I had to stayed an extra night in SF and arrived one day late. Also I had to flight back JFK and not Newark since they didn't have flight to Newark until very late the following day. A real bad experience on this flight. It took me 2 days to get back home.

The flight was delayed by more than two hours. A notification ahead of time would be most helpful.

Plane hit turbulence diverted to Houston. We'll probably get in after 3am

Given incorrect gate upon check-in, corrected by the gate attendant, D6 rather than D5, minor inconvenience. As with the previous flight, passengers were admonished to voluntarily gate-check carry-on luggage with the statement that those in the last boarding group would have no choice but to do so. If the Boeing 737 MAX8/MAX9 doesn't have room for carry-ons it's an interior design flaw on the part of Boeing. Posting an advance warning would be helpful, such as "Boeing 737 MAX planes feature limited carry-on space. Please be aware." SFO's amenities and TSA much better than MCO's. Crew was amazing! Brought my own food because Alaska's onboard selection has soy in everything. Beverage service was excellent. This was the first and last trip with Alaska after the previous flight's issues. It's no reflection on the crew of this flight. They were great.

The flight was mostly smooth and quiet. No seatback screens.

I enjoyed the leg room at my seat, but I was in an exit row.

Boarded the plain and had to wait 1 hour for crew Captain to arrive from another flight

They canceled the flight 30 minutes prior to departure without any heads up.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

There was a loud squeaky sound the whole time we were flying.

I didn’t not like that I could not select my seat and ended up with the worse seat.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

Plane was late because of a mechanical malfunction and the food listed as available was not. Flight attendants seem over worked and under paid. They just done seem happy. And that can be seen in their faces.

Waited 3 hours on a plane to de-ice due to manpower issues. Waited another hour and a half once we landed because of a gate issue. Missed my connections. Created. A total of 13 hours of delay.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

Like most domestic flights in the US, you are basically on your own with this airline when it comes to food, so be sure to purchase meals and drinks ahead of time or expect to arrive starving and dehydrated (like I was).

Flight was delayed due to the late arrival of the catering truck, which is quite unacceptable. There was a beverage service, but no pretzel, or cookie, or nuts were served in coach.

On time take off…US cabins look tired and need of refresh!

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Awful. I got stuck next to a person carrying a dog and behind someone with a dog. People need to board these dogs downstairs. The cabin is crowded enough with your pets

Packed in like sardines, very uncomfortable. Sitting the aisle my shoulder was rammed into numerous times by rushing flight attendants. Also flight was very cold.

Airline did not explain reasons why flight was delayed two hours. Explanations were badly needed and rarely provided. Problem seemed to clearly be the airline’s fault and not the fault of the weather or airport.

Very uncomfortable seats and seat backs, and I am only 5’9”. Delayed due to crew issues, spent a long time with no ventilation. Teeny overhead bins. Wifi worked well. Arrived safely.

I was delighted that we were able to get on the 4:40 pm flight rather than our original booking at 6:55 pm!! Other than that, the flight was comfortable and landed early😊

Our flight was delayed many times throughout the day. The final delay was about 8 hours. I spent time in line to speak to someone at their understaffed desk, and also spent time waiting online and then chatting with a service rep. None of the United employees were any help at all. I desperately wanted to go get rest and possibly re-book my trip but I was denied any compensation or voucher for a hotel. I was repeatedly told it was not United's fault and therefore they had no compensation to offer. Overall, a cold and callous experience.

The flight was delayed several times without explanation. The seats were terribly uncomfortable and wifi isn’t included. All these make for a less than ideal flight.

Internet service was erratic. Crew service was poor and slow. My luggage on this non-stop flight was lost and not recovered

Flight was 1/2 hour delayed leaving Phoenix. Otherwise it was an average flight. Flight crew on this trip was very nice.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

The experience was great and much better than the flight going out. of course I was in first class but the service was excellent

Comfort of seats, ease of boarding. Food selection could be better

Food options were limited which is absolutely embarrassing for a Flight of this size The staff did not come around as much and I am not accustomed to such poor service from American Airlines Drinks I believe were limited to soda and water

Crew were attentive and friendly. Flight was smooth and early! I enjoyed the less crowded plane. Thank you!

We are gluten free, there were not any available complimentary gluten free options.

No meal on a cross country flight? SFO-MiA is pretty much the definition of a coast to coast flight. No meal provided. Sky high wi-fi rates too. Stop nickel and diming your customers.
