Wish the underseat compartment don’t have a restriction, can fit a personal item such as backpack fully like most Boeing

Crew and service excellent. 2 hour delay for takeoff. SQ app showed flight on time.

Food from Surabaya was below average but from Singapore is much better

The usual excellent experience with Singapore Airlines. The airplane was on time and actually early to Haneda Airport. The onboarding experience was pleasant with no delays, perhaps owing to the fact that the flight was not full. Nevertheless, the air crew were their usual outstanding standards in serving the passengers.

Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options

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.

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

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

Everything was great keep up the good work 😁, can't ask for more.

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.

My flight was suppose to be at 7:45pm to fly but it didnt fly out until 8:55 to dallas so then all of my other flights was late and delay ihad to wait at the airport for extra 14 hours to be able to get on a different plane

There were delays at boarding and landing. These events resulted in a tight transfer time in HK. Poor signage for transfers. Finally, lost luggage at final destination.

It was good. The planes needed to be updated though, they were dated and the entertainment systems were old. Service was amazing. The pre-booked meals were lacklustre.

Super delayed. Unnecessary. Need more competent people doing logistics to keep things moving on time. Totally unacceptable.

Flew from lax economy on cathay 777. Seat configuration 3-4-3. When the forward seat reclines it feels like someone is leaning forward and staring you. If you are slightly big tray tables will touch your abdomen even with seats upright. AVOID this above 777 configuration at all cost for a long flight. However their Airbus 350 3-3-3 configuration felt spacious and Seats wider.

Crew on this flight dedicate their business class service to their high priority members. They would get priority service even the seats are behind me, and meals priority service and orders. I get the left over choices. I refused to eat because I felt discriminated, never booking this airline.

Leg room wasn't that great. Other than that it was a good flight

If my return flight was not so much better, I would have given an excellent review.

A lot of things Never flying with this airline again Had an emergency landing

Seats in the absolute back row of the plane even though we booked ages ago :( Crew was awesome though

Best international flight I have had in a while! Far superior accommodation, services, food and general experience compared to U.S. airline companies.

Very nice crew and great food. Easy to board just wish the flight could be shorter or seats more comfortable or more room to walk around when you get cramps in your legs from sitting so long. Crew was great and attentive and really was good food.

Everything was fairly easy just hard when you get to Heathrow not know your Gate number until an hour before but otherwise really everything great. Did not get my texts in time though to do me any good but that is why I still like everything the old fashioned way and print everything out.

Food used to be better and comfort was not attainable after 5 hours everything starts hurting.

horrible.. they cause such a problem and my daughter 14 years old was stranded in san francisco

I can’t even the whole trip was a catastrophe

Poor. Seats uncomfortable. No leg room. Hot and humid the whole trip. Food and staffs were ok.

The seats were so close together, when the man in front of me put his seat back, the screen in front of me was 9 inches from my face. There is no way to lean forward if I needed to pick something up. It was pretty uncomfortable for a ten hour flight. I was very surprised.

The food was good. Most the staff was pleasant. The flight would be drastically improved with WiFi on a long international flight.

When I needed to get my bag off of the plane so that I could take a train because the connection was 4 hours later, they took 2 hours to take my bag off making me take the train and miss my flight simultaneously. The seat size on the plane is too small for an average aged woman let alone a middle-aged man. It's unacceptable and I will not fly Boeing again.

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I was travelling 3.5 years after. Agree Economy is no business class but the food was mediocre. Ordered a Hindu meal, the salads were bitter . The food was really below quality and had no tast from what I had in the past. Indian Railways probably have a better quality food when compared. However the kids meal was really nice and really appreciate how they were taken care of. The restrooms were dirty .

My flight was with American Airlines 120. The flight was delayed 3 hours and I missed my connection. When I arrived in Doha, the AA staff told me to call an 800 number to rebook a different flight, which was unacceptable. Eventually a Qatar Air staff member helped rebook me on a flight to Manila, that was 12 hours later. They offered me a hotel and meal voucher which I declined, because I didn’t want to leave the airport. Long story short, I spent 12 hours in the Doha airport waiting for my next flight.

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

Reason for travelling Tampa to Orlando is to fly Qatar Airline. we end up with American Airline. This was the miserable experience I ever had in my entire travel history. Flight attendants were rude. They hit my knee with the food cart and I was holding ice pack for 2 hours. I still have the pain after a week. WE boarded the flight twice because of the temperature inside the plan.

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

it was like a banya -so hot... They did provide a great experience with special food. one toilet broke midflight In general it was a peaceful and relaxing flight - for business class it was good.

Chicago to Istanbul was a much better experience than I expected since I’m more accustomed to Qatar Airways business class. The business lounge in the Istanbul airport was amazing - loved the lockers and phone charging stations, and the bathroom was a spa experience in itself. The onward leg from Istanbul to Karachi was utterly disappointing. Terrible plane, and I felt like I was in economy - the seats don’t come near to lying flat and the food was mediocre. What a sad downgrade - it isn’t as though the ticket on that leg was cheaper. So, on that front, there’s no contest with Qatar airways.

Second leg of Turkish Airline with Indigo is disaster for following reason. 1) You have to carry your cabin bags through ladder to boeing 777 because it was parked somewhere in parking lot and was not given a gate to board passengers and this seems to be people traveling to and fro from those flights and is not issue with flight itself. 2) I choose non vegetarian food on Turkish portal way ahead of checkin to entire trip, However the Indigo flight gave me random veg food saying they code veg food code from Turkish. 3) Indigo did not served any alcoholic beverages stating some weird reason which is non nonsensical. 4)Indigo have TV screens in front of you but it displays nothing except "Welcome Onboard" with annoying white black ground in dark flight. This is the most stupidest and annoying part because you are held hostage for 7 hours and only thing you could do is stare back at white screen which does not have entertainment package or even flight tracker. Such a shame.

nice and clean plane but the seats and the comfort was not what i expected. i expected more based on all the ads and reviews that i've read. I guess you get what you pay for in economy.

Overall it was good. Food was bad. I ordered gluten free vegetarian meal. But I got gluten free chicken for my long flight from Seattle to Istanbul. I don’t eat any kind of meat. Second meal I got eggplant with meat which I couldn’t eat. I don’t understand why we can’t get gluten free vegetarian meal for a 12 hour flight. I eat the bread and that was it.

Worse worse worse, i would not recommend this airline to anyone. Istanbul airport maybe State of the Art facility but staff is rude, only works if they get tips, and they push you to give tips even though my family had spent $50 in tips. Airline staff doesn't speak english so you really can't understand them. It was a nightmare travelling with Turkish. Never again.

As a big guy the seats are way too small for me. Would prefer more comfortable seats on these long haul flights.

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

Boeing 777 is a bad choice for a such a long flight.

The staff at IST airport could have been more helpful. Too much wasted time and the plane from IST to KHI was just horrible. The plane was not clean and smelled bad!
