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.

The food on this flight from NRT to ICN was average. The staff were very friendly, but the flight took about 60 minutes longer than it should have because the pilot was only flying at 330mph instead of 500-550. Not sure what the reason is for that, but it meant for a much longer flight.

Best service I’ve ever had Flight attendants are nicely dressed and look very professional

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

Our seat row plus one ahead and behind we're completely overlooked during beverage service...

Need to have space for Cary on when traveler boarding any zone

The overall experience was ok, though there was certainly room for improvement. My husband was asked to check his carry-on bag at the gate due to claims that the flight was “full.” However, upon boarding, we observed ample overhead space and several empty rows of seats. This made the request appear unnecessary and caused some discomfort, particularly as he was the only passenger singled out for this procedure.

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.

Thankful for the staff who provided blankets cause the plane was quite cold and no way to adjust the airflow in the seats next to the bathroom.

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.

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.

Except for the uncleaned tray, and the delay in serving food for our section (which may have been due to the location of our row) everything else was good. The crew were very professional and responded to our requests promptly throughout the flight. We as a family were not disappointed by Emirates.

It was great, a little more leg room would have been better particularly since we were in premium economy

The boarding process was smooth and the stewardesses were nice. Some delays with drinks at the end of the flight, but no issues.

Thay crew was so nice.Air hostess il ham was so nice.my mom was little scray with airplan turbulence she help us alot.

Seat 💺 was all the way on last row. Food was okay .

Charged for internet that never really worked. The food selection was just ok.

Boarding, seats, entertainment and service were all great. Food was great except for the fact that there were too many sweet items.

The entire crew went above and beyond. This was our first flight with our 3 month old, and they were accommodating and friendly. The crew is attentive and marks a HIGE difference to the regular runs with Avianca and LATAM.

Business class on this plane was adequate, service, amenities, swag, and crew was amazing!

Airline did not have enough vegetarian meals for all guests, and crew were not adequately trained to handle this.

Very punctual, the onboard staff was friendly and correct, the flight was fortunately very calm, the toilets were clean, in short, an excellent experience Thanks

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.

Very nice and friendly crew. Boarding system can be improved.

The Etickets had been changed (Why?) without notice ; Hence, that caused troubles when checking in. Not until I contacted my ticket agent and was given correct Etickets could I then check in.

Cleanliness of seats, trays, storage pockets need more attention, but everything else was good.

A great airline, no complaints at all. My experience with Cheap Tickets was very disappointing however. Two hours after purchasing the flight they called to tell me that the ticket price had gone up. I’ve never heard of such a thing. That is called false advertising; I will never use this ticketing service again and will warn all friends to never use it.

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

Good overall flight. Excellent crew. Food options could be improved.

Vegan food tasted good. Restroom could be kept cleaner. Seat tray table was a bit tilted so food tray kept sliding down a bit. Flight crew can be a little more friendly, caring and approachable. Their faces lacked smiles and tone was stern.

Flight was delayed then we had to redirect for medical emergency during which time we had no information on what is the plan. The connecting flight was also delayed.

Never can get flight and nof light for three days .finally travel by bus. Very bad experience.

Food not of any international or even Indian standard. We have many cuisine available but only paneer & sundry items. Improve & provide some good indian items. Entertainment website or channel out of order.

First and the foremost I was shocked to see airindia standards have come down so low . The food was horrible . They served us 3 meals for vegetarian and all the was paneer . The orange juice was not at all cold it was smelly . After you take this heavy price air India should learn from other air lines . I at one point felt like throwing up . After all this when we landed we were not given landing slip . We had to wait for 45 min at the immigration just because no one was given landing slip . To top it all we were 3 passengers and had checked in 4 check in luggage . Out of which 3 have not yet arrived . Basically status says the loaded it in our flight ( this was a direct fight ) and it never reached . We are still waiting . There is nothing great to tell about our flight . The he only good thing was the crew were very helpful .

Lay out shows 1st row and second row given after taking payment. It's a fraud

The seats were extremely uncomfortable. Air India seats used to be very comfortable . with sufficient legroom. In this aircraft there was no legroom. It is a shame that for your profit margins you are trying to pack people like cattle on these long haul flights. The food was terrible. The bread was hard like a rock. Mr CEO of Air India, why don’t you take a flight in economy from India to USA and experience the hardships first hand. It is utter disgrace

Absolutely nothing. Cold and unpleasant airline staff, and to top it all, the entertainment system was broken. Really harrowing experience.

BAD experience. Entertainment system was not working and most of the passengers had this issue. Staff was not helpful. Meal was yuck. Bad old flights.

Overall good experience. I got first row seats with extra legroom. It does make a difference. Entertainment system was working. However, they kept serving me a VEGAN meal instead of a VEGETERIAN meal. I asked them and showed my tickets that Vegeterian meal is selected but the staff didn't care. VEGAN meal was medicore and not enough to fill tummy. Also unhealthy with butter made from palm oil.

Communication was terrible. Flight was delayed for 4-5 hours in DC (on the front end, and also after we boarded, we had to get off - some issue with fueling the old plane correctly). There was little to no information on timing or what was happening. Once we reach Delhi airspace, apparently there was weather that caused us not to land - we were actually near the ground, saw the run way, and lifted back up to the sky after being sooo close. Then we circled for about 30 minutes, and they decided to go to Jaipur to land until the weather cleared and to refuel. Again, once we landed in Jaipur (wrong city), there was little to no information on timing or what was happening. Then we heard that the crew was reaching their 24 hours. We sat on the place, on the tarmac for another 3 HOURS, with no food and not enough water for everyone on the flight. Then, they kicked us off the plane with no plan, in the wrong city. We went thru customs, got our bags (thank goodness), and had to ask a bunch of staff what was happening and what to do. Eventually, their soltuion was to bus people back to Delhi (like 6 hours we were told) but not everyone would fit on the bus, and unknown timing on when it would leave. At this point it was 9PM (we were scheduled to arrive in Delhi at 11AM...). My husband and I decided to risk it and take a cab that we had to pay ourselves (about $200 US dollars) to get to Delhi (about 5 hour drive). We both had terrible trips back to the US as well - almost missed connecting flight, forced to pay for carry-on luggage (a small back pack!) and duty-free goods by the Air India staff last minute. Just terrible experience all around. Never again with AI! The ONLY good thing was the air hostesses were kind and patient - example: they made sure people with food allergies got their correct.

It would have been perfect if there was onboard entertainment.
