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.

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

Honestly, I didn’t expect that I will experience this long time wait during the check in. There was only one person who was taking care of the passengers for the economy class and it took us to wait about one hour to do our check i. As a result we barely get to the airplane as the gate was at the end of the airport. That is totally not professional where one crue is working at the registration desk with economy and 3-4 crues are helping for the business class.

terrible. Because I felt very unwell during the flight. How do they leave a woman alone in the middle of 2 men? an obese man who was falling on top of me.

They put me on a chair in between two men, one overweight who was almost falling on top of me, and the other was even uncomfortable because I was half falling because of what the other was pushing me. I stayed with. my feet were swollen from fluid retention and from being unable to accommodate myself. it was very uncomfortable. I asked for help but they told me that the flight was full and they couldn't help me. I got off the plane almost unable to walk due to the inflammation. and then at FLL airport I asked for help because I couldn't go to my next flight, which was a connection.

The walk from baggage claim to the taxi is very difficult for older people I will never fly into JFK again. It is physically challenging

Overall fine but both ways for this trip was delayed.

Flight was delayed by almost 5 hours. Suitcase was not loaded despite the flight being near empty (my colleagues’ suitcases did reach JFK, unlike mine). Had to argue on phone to get JetBlue to deliver the case to my hotel. Never again

The flight was excellent. The crew was welcoming and attentive.

Great! I love Jet Blue. My favorite airline! Very efficient, clean and timely.

Run out of snack choices. Why are the seats not padded for your butt? Are we sitting on blocks of wood or metal for $250-300 a pop? This ain’t spirit. Let’s get it together people

We were told that our flight would be delayed for 90+ minutes because of weather, so we went to get something to eat only to have them randomly start boarding 15 minutes after the announcement, with no warning.

Entertainment... No earphones passed out. Many including me couldn't use the TV. Legroom was good. Crew was indifferent and a bit surly. Free wifi was a nice convenience. Check in desk location was unknown. Gate number on the boarding passes was wrong.

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.

Not sure why JAL partnered with American Airlines because their service is no where near similar. Flight attendants were not friendly and didn’t smile. Food was horrible…

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.

I love air Canada. The staff is so helpful and friendly and attentive. I paid for extra room but chose a ser near a person who took up a lot of space which gave me less space than regular economy, I was sad I did that!

No meal. Flight crew was wonderful, happily finding me storage for my guitar. THANK YOU!!!

Flight was delayed for almost 3 hours. Communication of gate change was poor. Email and screen said one gate and it was a different gate from that. Gate changed first to 64 B and then to 64 C. Originally it was 68B. 64C was not communicated properly!

Plenty of room in the exit row. Sat on the plane an hour before taking off.☹️ Landed late and had to wait for gate availability.

Flight was on time early arrival better entertainment good staff.everything was excellent

They canceled the flight on us very close to the flight date .

My experience was pretty frustrating because the first leg of my flight on United (though booked through Air Canada) was delayed causing me to miss my connecting flight on Air Canada. This could have been an easy solve as there was a direct flight later that morning via Air Canada that they easily could have put me on which would have only gotten me to my destination 2 1/2 hours later but because United and Air Canada don’t seem to have good communication they gave me the run around both telling me to talk with the other which I did three times to no avail. I ended up taking the delayed flight and getting on a new connecting flight which ended up getting me to my destination 6 hours later and I missed the event I was planning to go to this evening.

Everything went smoothly and as expected. We were on time and one flight arrived early.

This is not a Business Class equipped airplane and even the crew apologize before take over BUT BUT Air Canada charged full business class fare

Very good other than we have to wait for one crew and we’re delayed and the pilot and his co- pilot has to make a difference to be right on time arrival. Disappointed about no food service also.
