Uh there was a delay, because of the weather. And what took usually an hour flight to Louisville took about 6+ hours. Flight got canceled

Uh there was a delay, because of the weather. And what took usually an hour flight to Louisville took about 6+ hours. Flight got canceled

I had to get rerouted because the weather delayed my flight enough to miss both of my connecting flights. I select nearly 2 hours on customer service trying to get rerouted and had to miss my first plane which took my luggage to San Francisco. Luckily, customer service sent me to the same airport but I had to ride 12 hours in economy after I paid extra for premium economy. Totally sucks that I overpaid. Customer service and airplane crew were great and really helpful though. Although I still hate how small the seat was, especially since I'm smaller than average, I can't imagine how much it would suck for an average sized person.

Flight attendant took good care of my mom as she boarded on and off the aircraft from her wheelchair. I did not care much for the food nor the movie options Available. I appreciated the increased legroom available in economy. This was one of the main reasons we chose the airline. Overall, the good value and I would fly again.

I stopped flying with United back in the nineties. Today's experience reminded me of why.

ANA was fine. LAX has some major problems. I needed a wheelchair and BKK and Narita were very good. I do have to remember NOT to tip in Japan. LAX however, was poor. first the attendant wasn't able to push me. The next person left me stranded in several locations. They would just leave me where ever they felt like; No logic to these locations. finally when we cleared immigration, they (there were several people who didn't seem to care about their job) left me in a large room with a baggage carousal. I tried to locate my luggage to no avail. meanwhile my connection was getting closer. I finally talked with Emir from ANA and he showed me to my carousal which was located a few rooms away from where LAX personnel stranded me. Emir also found a good wheelchair attendant to take me the rest of the way. Without Emir from ANA, I would still be stranded, given the amount of care shown by the first wheelchair attendants.

I was very happy with my flight on ANA. The crew were excellent and very helpful throughout the flight. The food was also very good. The seats were comfortable and had excellent legroom. The headphone jack position was annoying, but that is a minor nitpick. The movie selection in the IFE was good, but the TV selection was lacking. Adding English subtitles to the Japanese movies and videos would have been very useful.

The cabin was hot. I was sweating during the whole trip.

The ehole fliht went smoothly. No delays. Bur the food was not good.

Just okay. Staff is accomodating especially at the check in counter and gate. Boarding was just fine. Leg room was cramped at economy. No entertainment, wifi is so-so. Cola in can given by cup, but rest of can was not given. At least give the whole can.

What I noticed is that when customers or passengers are asleep, they are no longer given food.

Food choices were very limited. Taste of the dishes was average.

I liked all the informational texts. I always knew where to go and when .

Not as good as expected Air Can needs to improve totally rated on internet as worst

Received an email the night before showing that there would be seatback entertainment on our flight. We get on and there was no seatback entertainment. And then it was a scramble to try to set up the iPads for the kids before takeoff so they could watch something for the four hour flight.

The reason I don’t fly United. No in seat entertainment for a long flight and inconsistent WiFi and entertainment available from my device.

It was 4 hours late. Almost missed my connecting flight no food or drinks on connecting flight. Overall terrible experience

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

The food for long haul was poor compared to Singapore airlines economy. Pasta plain with tomato sauce . Singapore airlines give me Hagen dash small ice cream cup it was great. The choices of dinner course Singapore air also much better The crew mostly friendly. The economy seat are as expected.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

I was at the back of the plane with earphones, and I could still hear the chatty flight attendants; I wasn't able to sleep at all.
