SEA HND sector internet only worked for the last 2.5hrs of flight….. never had this kind of incident with other airlines

SEA HND sector internet only worked for the last 2.5hrs of flight….. never had this kind of incident with other airlines

12 of the 14 hours were in the dark, all during daylight. Didn’t use my light because it disturbed other people it was illuminating. 14 hours sitting upright in a cramped space was horrible.

I’ve always had pleasant experiences with ANA and that has made me a loyal customer.

UA discouraged people to choose seat on economy class by charging about three times of another airlines. For example, ANA will charge USD60 to choose an aisle seat but UA is charging USD 219.

Roomy airlines. Friendly staff. Timely service. Temp was warm during the flight.

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.

The neck support for the economy seats is poorly designed. It’s hard to sleep even on inclined position.

Very good flight. Very uneventful which os what you want.

Flight was on an ANA flight not air Japan. They did most excellent. Again the flight had excellent legroom for someone that is over 6 foot tall and the staff was very very nice. The only issue you may run into is that the person sitting next to you, may not be able to speak the same language as you.

Same food options being served during connecting flights from Singapore-Japan & Japan- Singapore after one week despite different travelling hours . Rather disappointing.

It was crowded… the bathrooms dirty and smelly. The seats have been made even smaller.

The crew checked the immigration laws very quickly for Russian citizenship and confirmed our FVTF for Singapore for 96 hrs. Thank you.

Good overall. Seat spacing a bit tight between IST and ISB.

Excellent staff despite some trying passenger situations. Very impressed with their good attitudes and kindness.

it was great honestly for the melbourne flight a kit with blindfold and slippers was probided to each passenger on the seat and the food was really great will definitely recommend people take turkish airlines for travel not just on the sin-melbourne route.

Service was slow and checked bag was off last evening when flying business

Ordered Vegan meal - it was ok, but not exceptional. Seat ok row 39 middle section aisle. Nearly full flight - crew was busy but they did the best they could. There was a USB A port at the seat. I listened to my own music and only looked at flight information. One nice thing was the connection information was made available in the screen.

One of the worst check in process at the DIA as well as the boarding counter Changed seat at the last minute and assigned middle seat while I paid for window seat. Requested many times but to no avail . horrible customer service and very poor process Requesting refund for seat that was changed last minute

Seats are not clean inside the very dirty and need to improve

Pretty standard for long haul international flying. Food was fine, tv/movie selection was great, wifi did not work at all, crew was pleasant enough.

Flight was delayed “due to earlier delays of that plane”, so we were nearly three hours late.

I needed internet for critical matters and it never worked.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

The entertainment they offer could use some games, and maybe they could add some cookies to the snack menu. And the automated messages are a bit repetitive. But it was comfortable temperature wise and the seats were comfortable. The crew is very polite and helpful

This planes staff was top tier. Everything went great and had a great flight home.

It was perfect! United Airlines staff was extremely caring, super friendly and professional

Destroyed my suitcase. Tired of talking about it. Cancelling my unite mileage plus account.

Food is very bad and entertint not too many options ... flight attendet service is not good

For a 17 hour flight, they kept us well feed. The music selection could be better curated. The entertainment selection was about what is expected. The crew was fantastic.

I forgot to pre order gluten free on a 16 hour flight and I am pretty sure the crew raided their own lunches and first class to keep me fed.

Multiple delays and flight cancellations meant that I arrived five and a half hours late at my destination. There was limited communication from the airline. The airline left my checked bag at my departure city and stopped tracking it almost immediately. The airline has made no apparent effort to return my bag despite filing a report, and has provided no communication or ability to check on the status of the bag.

Food options were ok but the actual meal was terrible. On my way back, they simply said that there was no vegetarian option; somehow they struggled to get one meal and did not give me any breakfast at all which in my opinion was terrible. Never had such an experience in the recent years.

1didnt have wheel chair I ordered wheel chair in my ticket flight

Extremely disappointing. My original Denver–Vancouver–Bangkok itinerary was cancelled due to a crewing issue. I was not proactively supported and had to drive back home after already reaching the airport. Communication was poor throughout, and attempts to contact customer service resulted in being on hold for nearly three hours without reaching anyone. Instead of being rebooked on the same direct routing the following day, I was rerouted onto a much longer itinerary via multiple cities and airlines, which resulted in arriving approximately 30 hours later than scheduled. At Denver airport, there was no visible Air Canada representative available to properly assist. Ground staff offered no real support beyond directing passengers to a phone number. There was no clear communication, no ownership, and no meaningful customer care during a major disruption. The final journey involved three flights instead of the original two, significantly increasing travel time and stress. Overall, the handling of the cancellation and lack of customer support was unacceptable. What could have been better? Clear communication during the cancellation Accessible customer service (phone support that actually answers) Proper in-person assistance at the airport Rebooking onto a comparable routing rather than a significantly longer one

We had a very long delay. First the inbound flight took a while, then maintenance, they “fixed it” to then do boarding and leave the gate, and waste a lot of time to have to go back to the gate and eventually deplane. Had to wait for a new aircraft, wait for a gate, and do the whole thing again. Instead of leaving at 9:50am we left until past 1. I could’ve not woken up at 5am, or spend some more time with my family if they gave more grace period of time between flights to give some time in case of any issues. But they have to make all and every dollar possible

Comfortable seats and movies entertainment available. Better experience than the flight from Toronto to Denver.

It was delayed by almost 90 minutes and that messed up our plans but it was beyond UA’s control that is what we heard

Terrible experience. Flight was delayed then canceled. They had no clue how to rebook us. Had to wait in line to take to a gate agent for 2 hours. Absolutely terrible from start to finish.

Most expensive flight… and they are trying to pinch more and more money out of you. Baggage, snacks, pillows, headphones… — so many airlines do far better than this… surely a national airline can do better?

Overcharged by either United or Air Canada. Abuse of access to my credit/debit card.
