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
This was a large plane with an upper deck. It seems like business was upstairs. If it was a US airline then I would say I sat in economy plus, but I think it was just economy. Though since ANA would not allow me to choose seats for the price it may have been plus. Lots of movies to choose from, and good service.
This was the best airline I’ve ever taken. The staff are amazing. The food was great. The pilot was phenomenal. I would highly recommend this airline.
There wasn't much entertainment for my short flight but the onboarding process was smooth and the crew provided wonderful service. The seats were also reasonably comfy. Great flight.
Cabin crew were excellent in taking care of my mom as she boarded the aircraft from her wheelchair. Did not care much for the food served.
Great airline all together - triple 7 for a short flight was a plus - lots of room
Wonderfully pleasant experience. Good meal and beverage selections. Professional air staff.
Seat width can be a bit wider. not nice that they charge extra for the window seats. online check in can be greatly improved. in other words, their online interface is bad.

I paid an extra $100 for a seat upgrade including complimentary drinks, no drinks were served due to a few minutes of minor turbulence. They said they would return, they didn’t’. Sad…
The FTA in the JFK airport was so mismanaged. It needs improvement. Flight attendants should set age limits. In-flights snacks should provide two times instead one.
Self check in is not indicated well if you approach Terminal 1 from Terminal 2 Parking
It was very frustrating that the people that got in th plane before I did had all taken the storage area above my seat so I had to go all the way town to store my luggage. My seat was 7c and I had to go all the way to 16 to find a place for my carry on. How is that even allowed! The worst part was trying to get my luggage when we landed.. such a headache and so unnecessary. If I’m in row 7c I should be able to store my carry on above where I’m sitting. It’s ridiculous that o need to go all the way down and struggle at the end of the flight to get my carry on.
The flight was great, the crew was great. Our complaint was that there are no TV screens built into the seats. We used our tablets but drained my battery just watching a movie. The movie and TV selection were okay but not great.
First time flying with any airline that has decent seating. Great experience crew was friendly and the pilot was as well.
Pretty disappointing as we did leave Seattle two hours late.
The flight was delayed by 3 hours and 30 minutes without any explanation.
An uneventful flight is a good experience although one of the pilots gauges wasn’t working right so we had a half hour delay—no one can foresee that.
the flight was delayed twice and then delayed from taking off.
This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.
Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.
The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.
It was an overnight flight and I desperately needed coffee before we landed, but Delta does only one beverage service, and that is shortly after takeoff, not before landing at 5 am.
A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.
Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.
The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.
After a 5 hour delay waiting at the gate (3 delays adding up) with no clear reason provided, we finally boarded flew 3/4 of the way to Toronto then were turned back to New York. As we neared New York, the pilot declared that it was his fault, something to do with timing and him not being allowed into the country???? How could the airline let his happen? They had hours to prepare and make sure they had a crew available for the flight! We ended up in Toronto a day late with no sleep.
The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.
Terrible and im avoiding them in the future. My initial flight was delayed causing me to rebook my flight and when speaking with the representative to rebook I explained this is the second time my flights were delayed and they did nothing to help me. I wasn't booked to comfort plus or given a voucher or anything. I was almost late for my meeting that I needed to attend on Monday because of the games delta played delaying my flights even more and putting me in the very back of the plane next to an extremely intoxicated passenger
Electric plugs didn't work. Entertainment system wasn't working
The design of the light switch on the arm rest is ridiculous.
The gate attendant let me walk right by her with a bag too big for the overhead compartment
Seats were comfortable. It’s was so cold and very uncomfortable. I paid 2000 miles for wifi service that was choppy the whole flight. Would like to be reimbursed for my miles Food was so disappointing. Three cold and terrible meals for $3000 round trip. This needs to be better.
Very good - being handicap it was very hard for me in a center aisle bulkhead seat that Zi was assigned think it was 29-G as I had a hard time opening the entertainment screen and tray table. 30-G would have maid it easier. I was assign 29-G as it was the only handicap seat without being charged even though I was handicap (disability)
Overall, it was a good experience. Boarding was good and there was plenty of overhead bin space for everyone’s carryons (even when we boarded toward the end). Only improvement would be to offer trash service more regularly.
Nothing, whole flight was a nightmare, was forced to check my carryon bag at the gate, staff was rude and unprofessional
David went above and beyond to make our flight the best that it could be
No food service almost missed because of first flight delays
Had a hard time finding my assigned seat. No attendants to assist.
Poor air traffic controller staffing led to a 50%reduction on flights so we got to wait 4 hrs for our flight! Very disorganized at the gate Poor communication with customers
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 both ways. Limited compensation for the 5+ hour delay. Will not be flying Air Canada Rouge, and don’t recommend you do either.
The boarding was relatively quick, the crew welcoming and flight uneventful. The omission of meals on all airlines is unacceptable especially when the flight is during a mealtime such as this one, (lunchtime), is unacceptable.
Everything was simple and easy. The lady at the gate was super friendly, I wish I had her name to share. She's a little older, dark-haired. You can tell she likes her job and would be a great influence on any young people training with her.
Everything was made rather simple, so I appreciate that. All the people I dealt with from entering the airport in Jacksonville to my lonnnnnnng walk to my next gate in Chicago were excellent and very helpful.
The whole experience what excellent, from Anjou at the ticket counter to the attendants on the flight. Although it was an older plane, it was a very good flight. One of the best flights I have had on Air Canada!
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?
Economy middle seat was so narrow that I could not sit back comfortably with passengers on either side of me. Over the 9-hour flight, with my body slightly twisted most of that time, my previously-healthy left knee became very painful, even though I got up to walk multiple times. The knee is still painful 3 weeks later. Otherwise, it was a nice flight, but I was crippled over my entire vacation.
