I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Not many people, so you can lay down on two seats

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

The flight was on time and very quick, as expected, but the leg room isn't great in coach seats.

Flight delayed going to Korea. No free WiFi. Other than that everything else is were good. I would love to fly with Korea airline again

Just a typical domestic poor flight nothing more. There is no food choices in such a flight. Crew doesn't really care if you are on-board or not

long flights are difficult but the crew and amenities made it a very good experience

ANA gave me an amazing experience. They are very good with customer service.

Everything was good may improve some alcohol drinks and amenities during fly

All the food seemed to have onions. I don't eat onions. Anyway, everything else was great. The biggest downside was the underpricer company that purchased the tickets from ANA. Underpricer never provided the United Airlines booking number. ANA was a code share and all our flights were on United. I finally was able get booking numbers from Ujuted on X. They saved me from the upsales underwriter tried to saddle my wife and me with.

The crew was amazing, really friendly and efficient. One of the best flights I have ever been on. They made the long flight comfortable and I noticed there were two birthdays on the flight. They gave to customers birthday cards and wished them a happy birthday. That was very nice to see.

Everything was great. Wifi was down,but that didn't matter to me.

The staff are very kind ,friendly and helpful .This is my first time flying with ANA and surely will fly again.

Hard to explain because we thought we were booking ANA airlines, not ANA operated via United, so we were disappointed, but for what it’s worth, everything went smooth and loved the movie selections. The food was okay, processed and full of preservatives, so vs what we were expecting with ANA it was different

The best best best flight experience I have ever had. And I fly A LOT. THANK YOU, ANA!!!

Excellent service and comfortable seats. Friendly and helpful staff. No food for a 3hr flight over lunch time which was surprising (or is that a feature of domestic flights in Japan?)

When booking the flight i picked it because it said flying with ana even on our e-ticket as well but I showed up to the airport and I flew with united. I have flew with both airlines before and I prefer ana for the food quality and comfortable. So I was disappointed in that outcome and felt the food gave me minor ibs. The whole thing was missing leading with not getting what I thought I was paying for. Felt a bait and switched. Do not have confidence in using this app in the future trips

They ran out of food and were offering random food to passengers.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

Worst experience I have ever had with any airline in over 25 years.

Very noisy and careless crew on this overnight flight. They should understand customers want to sleep

Everything was fine and I have no complaints or things to note.

The flight was delayed for 30 mins. The overall experience was good.

Highly impressive. On time. Smooth and fast boarding and disembarkment. Really great service

The economy seats are much indeed roomier. Meals needs improvement.

flight delayed 45 mins - missed connection - 1 hr layover became 8 hr layover waiting for next flight -

Fast boarding flight on time boarded plane back to front instead of stupid zone groups like US airlines do...

I love flying with United. Unfortunately, I flew on an older plane with minimal upgraded technology (no Bluetooth functionality or handy charging ports). Otherwise, the flight was great and even arrived early.

They changed my seats after I checked in and I was stressed from the time I saw that information until just before boarding, when the gate attendant fixed it, but it shouldn't have happened. And if it couldn't be prevented, then the people on the phone I spoke with should have done something to help, which they did not, nor did they offer me compensation, just meaningless apologies.

online check in was not available so i had to get to airport extra early. The flight was delayed and my luggage was lost. I had an argument with the person behind me who wanted to keep her bag on the floor and not allow my seat to recline on a 9hr plus flight. So overall, lots and lots of areas for improvement.

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

My flight was delayed a very short period of time but they did not hold my connecting flight to San Diego, also through United. So they closed the doors before we got off our plane. They would only have to help the door open for another five to ten minutes. So I missed a court deadline for a manditory mediation settlement conference for my client. I had to get an associate to be there in person and be on the phone with him relaying what he needs to do the entire time. The court was very upset with me and so was my client. United cannot be trusted.

Very rough getting into denver. my kid threw up it was so rough.

We were given vouchers we couldn’t use with a 5.5 hour delay

Cramped seat even in economy plus seat 10A. Over booked flight, no space for the bags

Why wasn't this flight departure scheduled eith another crew so that it could leave on time? When we arrived in Denver we had so little time between flights we had run to the connecting flight. We should received some credit for the inconvenience.

Really good 😊 the woman at the gate entrance was a little rude checking in our carry-on but i dont think she worked for the airline, she worked for the airport at sacramento, other than that amazing.

The flight was fantastic and the crew was absolutely excellent, but the entertainment system on the B777 was not working. That's a long time to spend with no electronics. The crew offered I-Pads but I had brought my own. I am only pointing this out because this is the second flight on Philippines Air where the entertainment system was down. FJM

Theairline, both at the terminal and during the entirety of the flight were kept at uncomfortably cold temps. Maybe between 55 and 60 f. Those who had traveled with the airline before donned puffer jackets, wool hats and pulled blankets from their carry-on bags. The seat back entertainment also failed on my trip, leaving me for 12 hrs. With nothing. Seats offered enough room (barely) for a 6'1" frame, but it was pretty tight But the worst offender was the uncomfortable temp..

The checking in agent tried to give me a different seat. She tried to give me an economy seat even though I had already checked in with a seat assigned and paid an extra $300 for those seats. She also separated our seating assignment. Very unprofessional and seriously a bad example for an agent. She was rude when I showed her my receipts and she made us wait more than 15 minutes before we were able to get the right boarding passes and correct seats (seats that we paid for in advance)!!!

Purchased exit row window seat for extra leg room and sleep. Worth the price. Attendants maintained restrooms regularly. No snacks/chips/nuts/cookies beyond what was served with meals.

Terrible check in and food was like from fast food

Delayed, from morning flight, they moved to evening. And said, their earlier flight is already full but we can upgrade the seat

I thought the meals and meal choices were excellent. The cabin staff was helpful and as is the norm for Pinays, extraordinarily empathetic.

Not so good, my business seat is not working properly

Well it's strange everytime going the flight is late coming back the service is superior

The staff was wonderful. Really took good care of me. The food was not my favorite.
