Delay for switching planes. Then delay after delay (mechanical) after boarding so that we were almost 3 hrs late, getting in at 230am. Crew was good.

Flight attendants made this flight wonderful. They made sure everyone had what they needed and anticipated future needs. They made adjustments as needed. It was clear this was an experienced crew.

Very delayed for seemingly no reason. Made me miss an event

we bought Mediterranean boxes for lunch. The salami in mine had gone bad long ago, but my partner had good salami and could eat it. Could I buy assigned seats? I guess that I didn't spend enough, so sat at the back of the plane

the flight attendant was so great and the upgrade to first class was top notch

There was no food or entertainment, thus thus the neutral rating.

The Alaska Airlines app made it very difficult to find my boarding pass. It was very frustrating to use! The flight itself was flawless.

No communication with delayed and canceled flights. Completely in the dark for the whole experience.

You need categories to denote when food and entertainment are not available.

Alaska is generally the airline I fly nearly all the time. I nearly always have wonderful experiences on Alaska and never a complaint. However, this entire flight felt like we were in the cheap seats the entire time and I had even upgraded to a cushier seat. For an over six hour flight (that became 7 hours) there was no online entertainment. I couldn’t connect to Wi-Fi and we were offered one snack and one drink. We were instructed to go to a particular baggage claim and 30 minutes later our bag still hadn’t come out and it turned out it was the wrong carousel announced. So overall, this flight was a series of mishaps really less than mediocre service even though flight attendants were wonderful.

Awesome! On time flight, early arrival, and a complimentary upgrade!

Paid for wifi that didn't work. No plug in seat to work. No entertainment.

We departed early and made up time in the air allowing us to arrive 30 minutes early. Capt was incredibly genuine and thanked every passenger for flying with Delta. Completely humble and professional!

Was forced to check in my small carry on, even though I informed the crew it has very fragile items inside

This was one of the worst flights I’ve been on in years. I upgraded to comfort and had such an uncomfortable experience. The person next to me was oversized - which I understand - however, they took up their space and mine. I could only use about 50% of my seat space to not be physically touching this person the entire flight and there was no spatial awareness. I also could not use the seat outlet because their body was obstructing it. It was very inconvenient. Their body kept touching me repeatedly during the flight and I felt very uncomfortable. To pay more for an upgraded space and then not even being able to use it was highly disappointing.

No wheel chair as requested at Atlanta arrival on first flight.

Only freetext wifi was available in flight; browsing WiFi required payment. Since the seats had no in flight entertainment, Delta should revisit this policy on this longer flight.

Only water, tea or coffee served midflight, even to comfort seating. Man next to me needed two seats and took up a portion of my seat and Delta did nothing.

Flight was suspended mid air for over 1 hour and it was late

The flight was great as well as the airline staff

Both of my flights arrived early and check in process was smooth

Terrible. No customer service, no food, no drinks on a 6 hour premier economy booking.

Short flight, but no drink/snack service. The flights both going and coming were delayed.

Much better than Spirit. I was please by the easy fast check in and boarding

Crew was great. 2 1/2 hour delay was due to staff needing "rest" was avoidable and self inflicted as United not willing to hire enough crew to keep flight on time.. Ridiculous. The crew and the passengers both suffered due to this.

Horrible Flight significantly delayed. Not due to united issue. But trying to rebook connection flight and get information about overnight accommodation was difficult. Agent did not seem to care or have any interest to help.

Everything was on time Will use united again for sure

Plane outlets in my row not working to charge phone. Staff response was, well it should be. Plug into seed for volume not working well. Had to find the sweet spot for plug in or it would shut off and on.

Fine not above and beyond as I had a connection that was delayed due to maintenance

The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.

The flight was on time/early, attentive crew, and everything overall went smoothly. Disappointed that WIFI was not working for the flight.

One day, I do so hope for a gluten free snack! Seems like with the rest of the world FINALLY figuring out what gluten free is, American Airlines would too. Fingers crossed!!

The flight was significantly delayed for 6.5 hours because of snow. There was no communication once the plane returned to the gate regarding when the flight would resume. Other flights were departing while our flight was being unloaded for reasons unknown. Our flight also seemed out of the queue regarding further deicing, refueling, and waiting to Taxi to the runway.

Flight was on time and the meal and service were good.

Food was bad, sandwiche with cold cut meat was not labeled and and none of the flight attendants could tell what kind of meat it was (beef, pork or turkey). People have dietary and religious restrictions and "I dont know" is simply unacceptable. One flight attendant was extremely rude and unprofessional. Filed an formal complaint withAA regarding his behavior

Flight was delayed for 2 hours, then last minute the change to on time. The satélite location is far and a nightmare to get to.

This was a horrible experience. I’ve experienced several delays at this point and still not home. I was supposed to be home by 8:30 last night and here I sit at 7 am on a plane STILL unable to go home because of American Airlines.

Generally good. Flight left on time and the seats are comfortable. Plenty of space in front if you in you choose a comfort plus seat, completely worth spending the extra money given the amount of hours the flight lasts. The food tastes good but I would say it’s a the amount is too little. The crew was friendly and efficient. There was a some turbulence at different points into the flight. American Airlines has good deals to NZ if you book with plenty of time before you plan on going.

the plane was so hot!! the air-conditioning was barely blowing. The flight was delayed, and we had to sit on the hot plane before take off for an extended amount of time, waiting on international passengers. Would not have been so bad if it was not so hot. They said it would get better after take off, but it did not.

They are always late and seats was also not having working charger
