One of the business class panels where we were sitting was broken and it didn’t close. Therefore, the be privacy was limited.

As usual the flight from AUS in Austin to SFO was late because they didn’t have adequate staffing to board the plane on time creating a 1 hour delay, which resulted in me missing my flight to Osaka due to a missed connection. When I got to the gate 10 minutes late after landing exactly the time the connecting flight was taking off, I saw my flight to Osaka sitting at the gate and that gates had closed. I attempted to contact United Via chat on the United App and was given the runaround and passed between 2 separate “agents” who after saying they could rebook me, told me I needed to go to ANA even though they’re partners and all of my ticketing was through United. After going to ANA’s gate at SFO to try and get help I was told I would need to leave and go to United’s ticket counter in order to get help. The ANA agents said that it was United’s issue. An hour after running to try to make my flight I got to the United counter. I showed the agent my itinerary and she helped as much as she could. I was booked on a flight that would occur 13 hours after my original flight to Osaka and given $45 in vouchers which doesn’t cover much at SFO. I had also spent 30000 miles with United to get an upgrade with more legroom. And that was not refunded to this point. Ultimately I lost 1 whole day of vacation in with my wife and kids and, the 30000 airline miles and I’m out the money and time I spent. In these situations United and their partners should go out of their way to communicate and accommodate but I was left to my own devices to find the right resources. The only option was to fly to Seoul 12 hours and take a connecting flight to Osaka: I am a United Skyniles member and would not recommend booking a flight with them unless you thoroughly understand the routes as it is likely you will be left to your own devices to resolve the situation.

I like that we made it faster than regularly scheduled. Everything else was poor. The boarding was slow and chaotic. One person was screaming instructions to people that didn’t understand and there was only one camera so boarding was slow. The crew was not very friendly and one stewardess was extremely rude to everyone the entire flight. The food was not good and not themed to the country we were going to like every international flight I’ve taken. Lastly the seats were awful. After this flight I would never recommend United and will actively avoid booking another flight through them.

Seat was broken. Check in was not possible until we reached the gate, by then we were separated.

Service is great. Seat is ok. Not much storage room and seat is hard but seat topper was nice. Cabin was very warm most of the flight. Washoku Food was good.

Entertainment and food is best. I love to use ana for a lots japanese movies…. Food was best

First trip from Tulsa to Houston by air. It went by quickly. I watched half a movie and continued the rest on the next flight. Staff was considerate and helpful.

Luckily I just tried to sleep. But the entertainment system was awkward to operate. I hate all this stuff with apps and adding it to your phone and all. It is a nuisance. I would prefer a good magazine or newspaper in the pocket in front of me or available.

Poor. We weren’t able to check in online (for several hours until we gave up) for no apparent reasons although our passports were loaded successfully. When we were at the airport check-in, a rep helped us at the kiosk but she disregarded the KTN provided to her so we had to come back for it after being questioned by the TSA person…

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.

On time, quick boarding, so nice of them to honor active and retired military with early boarding. Attendants were nice . Plane was clean. A bit crowded like all flights.

Everything was great except the fact that catering did not restock the flight from ATL to GRB and we were only offered water.

The WiFi on the plane was out. I also thought movie options were lacking.

These Delta 717 jets are ancient. No entertainment and you have to pay for WiFi that barely works and goes in and out the whole flight. Delta should be ashamed flying this garbage.

My seat was changed without my consent. It wasn’t a major deal but annoying.

It was delayed over an hour and a lot of announcements disrupting movie.

Delta has joint the nickel and diming airlines. The experience is getting worst by the day. 1,000,000 miles for a trip to Asia in Business Class where I got the same thing for just under 90,000 miles through an Asian airline. Where is Richard Anderson? Please come back!

Everything went smooth from check in, thru TSA, then boarding, and a smooth flight to ATL.

I had an extensive delay on my previous flight and we had another delay due to the crew not being there. We were scheduled to have a late arrival but due to the delay it was even longer.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

For a 17hr economy flight it wasn’t bad at all, thankfully it wasn’t a narrow body plane.

Weather delayed arriving flight and even though I made the connection, my luggage did not.

Really impressed with the Airline and much with the Crew. The crew was amazingggg, changed seats very easily, provided a lot of snacks on demand, the plane is nice and clean, the menu is well presented; unfortunately, the food is not fantastic, but it's not bad either but nothing to rave about. I am still rating it as excellent because I loved everything else; food improvement will be great!

My flight was delayed by 8 hours I arrived at airport 4hrs earlier but to see if they can reroute me to get my connecting flt to Hong Kong. They auto rebooked my flt. With no chance. Which I missed this entire reservation through kayak. My next flt they got me on was at 6 am. Misses an entire day of my trip abroad all my accommodations seat assignments were missed and missed adding my TSA precheck to my ticket as well as my vegan meal request so I didnt have meals on any of the flight....so not a comfortable experience. Please help me with accommodations upon my return.

The service was better on this flight from the long haul one, but still very poor from The Cathay Pacific of the past.

The plane was dirty, the seats were torn and broken, the service was the most terrible ever, the bathroom dirty, they will not even serve water you had to request it, the meals were terrible, overall less than Zero, I will never fly Cathay Pacific again.

Frequently flyer number should and could have been put on at the time of booking as I gave the number when booking.

I didn't have much experience with Cathay Pacific airlines because of delay and missed connections, the bulk of the trip was on Japan Airlines.

Super delayed. Unnecessary. Need more competent people doing logistics to keep things moving on time. Totally unacceptable.

I traveled to Singapore for 5 days, I didn’t receive my luggage until the 3rd day. When I received my luggage was broken which they fixed it supposedly. I never had such a poor experience with the any other airline. I honestly think it should be a compensation for all of my losses and suffering that I went through.

While boarding at PVG, there was a ticket checking by the gate, then there was another ticket checking right at the bottom of the escalator, which created quite a dangerous congestion. Don't understand why the duplication?

I was traveling alone with an infant, so the crew was incredibly helpful. Both the international and subsequent domestic flights were impeccable.

Pillow and blanket are dirty. My son got multiple bites during the flight

Excellent! I had read some negative reviews but I found out that it was not all was not true! The staff was courteous and helpful. The flight take off and landing was nice & easy. The food was good! I asked for a second and I got it easily and without an attitude! All was wonderful!

I was surprised and appreciate that they actually served a hot meal on such a short, early morning flight. The check in and boarding was hassle free and most of all my Alliance Status / Code Share was recognized and the revelant courtesy was extended; other than some needed attention to detail concerning the cleanliness of the cabin, and some unnecessary aggressive wording their safety briefing, it was an overall pleasant flight, and I would certainly fly with them again.

Flight was delayed for more than 3 hours, food was mediocre, seat didn’t recline

Lost Baggage - very frustrated…learned that bag was never put on plane.

Flight was fine, however we were not able to check in online, this adds to travel stress. Luckily check-in at Heathrow was quick, but we did not get the seats we paid extra for. We paid for a window and 2 aisle seats from Shanghai to Tokyo leg, but they changed us to middle seats. Not good :(

Again, I was presented with birthday pastries two times as a celebrated my birthday on both legs of my trip. I will keep flying to China using China Eastern airlines. As they made this trip a special one thank you.

It was my birthday while I was on the flight on China eastern airlines. They celebrated my day by giving me a personalized birthday card and also a very delicious pastry. I was surprised and thankful by the China Eastern crew! The whole staff was kind and professional? My second flight into China and the most memorable! Thank you-

Just having a little bit more legroom would've been nice.

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

Gate agent did not hold flight for connection, provided no assistance to get new flight

Nothing they cancelled my connection and couldn't get me on a flight for 3 more days

The plane was dirty and the in seat air wasn't blowing as planes usually do.
