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

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.

Check in was easy through self-check-in kiosks just like domestic flights. Staff onboard were fantastic. Some "book the cook" good options weren't great, others really good. Entertainment options a bit limited to what I've experienced on Qantas. Overall a good flight though, especially for the price.

The food options and quality could use some more excitement and variety.

Overall, very good. The food was better than expected with the exception of the pork and potatoes dinner at the end of the flight. My family all selected that dish and did not set it. I tried a bite also and it was honestly terrible. Also, it would be helpful to know when the snacks in the back of the plane are available.

Everything was good except food , food choices was very less. Washrooms were closed.overall good experience.

On time boarding I would like to see ground hostess to help transit customers to direct them to the right terminal and boarding gate. Last night, all the transit customers on SQ484 arriving Singapore had to merry go round to look for terminal and boarding gate to board SQ128 transit to KL Malaysia. We went to Terminal 3 taking the Skytrain to T3 and back to T3 to get out to look for different Skytrain to T2. On arrival t2, we had to go round to ask which boarding gate to KL. We only had 5 minutes to make to the boarding time at 6:55pm but we already spent more than 30 minutes running around to find the boarding gate. We were late at the boarding gate.

Timing very good from sfo to Singapore and service was awesome and economy class seats are great overall very good experience thanks

The seats were more narrow than at other lines. Food was mediocre (economy class)

Well organized boarding, efficient and on time. Nice crew on the plane. Thank you!

The Qatar Airways staff pre-boarding and also on the flight from Dallas to Doha were incredibly mediocre and arrogant. Consider retraining these individuals Other flights were ok.

My experience with Qatar airway was very unsatisfactory. They lost my child’s stroller and I was told they found it and will send it to the hotel which was a lie. I had to go back to the airport baggage claim and pick up myself after trying to contact them many times!. There was a lack professional and communication. I am very disappointed in Qatar airway and will not be recommending them to friends and family nor will I be flying with them in the future.

Worst air experience in whole life . Boarding and checking was hassle as they did 3 times. Crew team was clueless about passengers need. Despite of passengers raising hand , they were resetting the program

The food is not good and also if you ask crew to bring something they say ok I will bring but you will never get it. Please they should listen good to passengers

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

Did not like anything. Seats were crammed, leg space was minimal and food was terrible. This was the first time traveling overseas in American Airlines and was the worst experience ever. Have learned a lesson to never travel in American Airlines.

Delayed my flights and no communication. We end up spending 6 hrs in Doha. No food or any concern from the airline. Terrible

Check in desk people constrained by fear. Obvious typo on Uganda visa, even though approved, caused loss of flight. Something is definitely wrong with this system.

Between Air India and Qatar my luggage was lost for three days. I eventually found my own luggage location using the Apple Air Tag. Air India used a paper form to report my lost luggage. I could never get past getting past luggage personnel with my report number before they would hang up on me. Only after them specifically telling Air India at Chandigarh airport where my luggage was located which was right under their noses did they react. After three days I finally received my luggage. The Air India luggage folks didn’t seem proactive in finding the luggage’s rightful owner.

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.

When comes to Taiwan airlines China airlines is the best rest are pure trash

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...

Baggage delayed for 2 days and still chasing for reimbursement of basis items. Very horrible customer care service.

Horrible airline. Missed my baggage and don’t want to reimburse for the basis items. Pathetic customer service

Food was hood for airline food with good poftion and variety in meals. Frequency of beverage service was very low and amount of soda with meals was inadequate.

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.

Professional & courteous cabin crew. Food was very good even in economy class

7 stars hospitality and an excellent service by the Turkish Airline entire team. Somehow, our membership numbers for mileage points were not indicated on our boarding passes issued at O’Hare Airport by the Turkish Airlines check in desk. During transit in Istanbul, I brought to attention of customer service Turkish Airlines. Please have our mileage points posted to our membership account from O’Hare Chicago to Lahore for both my wife Kaukab Shirazi Thank you

Terrible boarding experience, with an incomprehensible assignment of priorities. “Fast track” was the slowest. Poor system planning.

Terrible boarding process, no proper line maintained even for business class, crews are not very attentive, business class food quality / variety / quantity have gone down, everything has become cheap.

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.

Food was unfit even for prisoners. larger front seats are terribly uncomfortable, which is ironic. Thorough need to upgrade aircraft on such a long route.
