Impeccable services, excellent meals, on-time flights, what more can you ask for!

Flight from New Delhi to Tokyo was mediocre. The seats were not of business class as we are used to. They were not wide enough. On the other hand the seats on the flight from Tokyo to San Francisco were excellent every thing were great except the food. Tokyo business lounge was excellent. The whole experience was great except the food on the plane. Will still fly JAL.

The entree wasn’t very good. The rice was soggy. The side dishes were all good though. The breakfast was also good. The crew were excellent, as usual.

The flight attendants were excellent as usual however the meal wasn’t the usual good quality. There is cooked rice was mushy.

This portion of the trip from HCMC to Dallas was operated by American Airline. Unfortunately they are 2 steps below JAL in overall quality. Regardless, AAStill got me where I needed to go on time.

Website from the 1990s, super frustrating customer support, inflight experience merely OK - more like United than e.g. Emirates

The seats are significantly more comfortable than US airlines and the staff are much friendlier. The food is also much better, as they are particularly accommodating to any dietary restrictions.

The team members are extremely attentive to make sure you have the best experience.

Could had been better if they include in their menu some western food.

They 7 seats in one row for Business class while most business class for other airlines are 4 seats in one row. the seat was narrow. the Toilet was so smell, dimming light, no water out of faucet. Terrible.

Overall the experience was ok. My two complaints are that the food is absolutely disgusting. The movies in the flight to Japan were a completely different selection than the ones on the way back. So if you’re looking forward to watching a certain move on the way back, think again.

That food is absolutely disgusting. Bring your own meals because the food not only smells fowl but tastes even more so. Jesus, I’d rather just eat a protein bar.

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

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

My wife and I liked everything except the cold breakfast

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.

The flight was smooth, but there were not enough options for meals and I was given beef when I do not eat beef. The flight going was much better because we received more snacks.

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.

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.

Horrendous. We upgraded and they took the money but cancelled one of our tickets. The recline action didn’t work on the seats for the flight from Singapore to London, pre booked meals but they seemed to have disappeared as well.. Phone customer service was horrendous. Took 5 phone calls and no fix. Craig at the airport was the only one who seemed to be able to get the ticket back.

Excelent service and plenty of food and drinks during the flight. Flight crew very attentive to our needs. Leg room between rows are very disappointing.

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

So happy I flew with Singapore Airlines. The customer service is top notch. I am terrified of flying and the staff made me feel so at ease. Will only fly Singapore internationally moving forward.

Food could have been better. Too many passengers getting up and down all the time.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

It was very good experience on board to Sydney with SQ.

Flight from SFO did not include entertainment as it was not working the entire duration of the flight. Was informed that there would be a $350 voucher for the inconvenience. Uncertain how the voucher will be provided.

It was an average flight. I would have expected more from this airline. Food, seats, service, etc was just average. I just give them some extra points for offering free WiFi on board with just a Krisflyer account.

Traditional economy class. Not a full flight so spare seats. Food and drinks were good

Was bumped to a later flight because of inefficiency on part of the airline.

Inflight entertainment, poor that there are no headrest screens on aircraft used for an international flight.

The Emerits/Qantas flight was cancelled to Wellington. We need a refund. Had to buy another airline ticket. How do we get the refund. Still not in Wellington.

Delayed QF59 flight once again, Qantas doesn't fail in maintaining there delayed departures and arrivals. USB points do not work nor do the power point sockets on the plane, Qantas staff admitted that on the flight. Don't expect to your charge devices. Saving grace, was the ice cream. Bottom line, if you expect to fly to HND and make it on time avoid Qantas and if you're interested in ice cream - visit 7/11.

Pretty excellent. I don’t know what the pilot could have done better with the bumping ( there was a storm) nor what happened to my ears coming down into bendigo. It doesn’t happen coming down into Sydney just the return flight. I wonder why?

Touch screens were very difficult to use, generally being laggy and unresponsive- it was quite an art to get it to play the thing you wanted rather than some thing at random. Selection of films and Tv was good when touchscreen decided to finally respond.

Their aircraft are old and amenities lack way behind other international carriers leaving from BNE. Even in economy

Airport and crew experience was excellent. We had to queue for the runway - no one’s fault, but it did mean we were 30 minutes late leaving

Overall good experience with flight and airport wheelchair staff. Also got Indian food in the flights

Good flight, friendly crew and overall - good service on United Airlines.

Received email saying that there won’t be a seat back entertainment screen and inflight WiFi would be available. But no WiFi both ways. Say it in the email.

Somebody either kayak or Air Canada booked my flight under my preferred name Betty instead of my legal name and I almost was denied boarding my flight

flight landed late almost 1.00hr and we 4 passengers missed our connected flight to indianapolis, we need to get the hotel and taxi for the next day flight to home in indianapolis, cost us $ 300 more

Or the greatest and it ended up picking us up from Chicago to Toronto not sure who was tesponsible for the 4 hr delay. United should have been properly prepared for a scheduled flight from Austin to Chicago and they were not.

Good, only discomfort was consistent turbulence through the 3 hour flight. Not sure if in companies control though.

From the kind young lady (w/Vancouver air security) who expedited our check-in to U.S. Customs to the Air Canada gate crew who gave us pre-boarding, the flight attendants who actually offered a strong hand to help me board once I had surrendered my rolling walker at the door, they are all reflections of the thoughtful, genuinely helpful Canadians we have grown to appreciate. Water and other beverages were offered throughout the flight to make sure we weren't dehydrated and the cookie was great. (Husband bought the fruit & crackers snack,) I was delighted to see three movies that I would not have otherwise seen and appreciate that AC left the last film viewable until its conclusion although the flight had actually landed. Last, mahalo to the kind strong gentleman who not offered his hand to help me debark the plane, but gave me an AC pin that I'll truly treasure.

The ground staff was so rude in Toronto airport ...very rude and did not answer simple questions, and made me look like a fool. Very rude ground staff.

My flight got delayed 5 times and then got cancelled eventually, I had to get a hotel and uber and pay for food for an extra night without any plans. It was a horrible experience, instead of Air Canada, I was flying with United .

I had a nice flight with free wifi. So I was able to message family members and stream music during my flight, which made the trip go by fast. I also enjoyed flying on there Airbus A220. The plane looked very new and it also got up to speed fast down the runway and didn't need much runway to get airborne.
