Scores according to KAYAK customer reviews
Pros: "attentive crews, clean toilets"
Cons: "waited for 2 hours upon immigration clearance, not sure what was the issue. ground handling only updated there was a delay. baggage didn't get loaded onto carousel until 2 hours after landing. horrible"
Pros: "The crew was friendly"
Cons: "Bathrooms could have some lotion for dry skin"
Cons: "Delayed flight meant missed connection and had to stay overnight. Very little communication from the airline about what arrangements were being made. Was also unable to check in online on either leg."
Cons: "My baggage got missing"
Cons: "I bought my seat assignment in advance, and they did not give me this seat on the plane. Before boarding, I asked at the gate if my new seat was a window--which is what I paid for--and they confirmed yes, my new seat was a window. Turns out, it was not, it was a middle seat. I asked a flight attendant to relocate me to a window seat, which she kindly did, however this seat was quite uncomfortable as I was seated next to a large gentleman who probably should have been required to purchase two seats. Overall, there were two issues with Qatar Airways during this trip: they did not give me the seat I had requested and paid for, and then lied when I asked if my new seat was a window."
Pros: "Absolutely professional!"
Cons: "Nothing all perfect"
Pros: "There are very friendly"

Pros: "The crew in the plane was very supportive and assisted us with the baby and have provided all possible comfort"
Cons: "we have booked a wheelchair to carry old grandmother with permanent injured hand and the baby to the plane, and we have confirmed availability of the same by calling QA office in Qatar. However QA did not provide a wheelchair during check-in at Paris Charles de Gaulle for whatever unjustified reason"
Pros: "The attendants were great."
Cons: "The food on all 4 flights was ok. Could have been more interesting recipes and dessert. The seats on all flights were consistently hard and stiff. It was impossible to get a decent rest because of that as well as the areas being pretty cramped."
Pros: "Crew was professional"
Cons: "Plane is dirty Food is disgusting Bags treated so badd"
Pros: "1. All flights were on time. 2. The aircrafts were clean and tidy. 3. The choice of entertainment was plentiful. 4. Possibility to connect to internet provided on outbound leg, not on inbound."
Cons: "1. The boarding process, in general, could be improved. 2. The "official" transit time was one hour, but passengers were made to wait while the business class disembarked, reducing actual transit time to 30 mins. Considering distance to departing gate, and security checks, this was stressful."
Pros: "Plenty of beverage service and food was very good."
Cons: "The other passengers were often rude and uncivilized. I guess Qatar couldn’t do anything about this."
Pros: "Seats are great!"

Cons: "Can't find any fault...Sorry!"
Pros: "Fabulous service from start to finish Excellent cabin, spacious & impeccably clean Super choice of food and drinks We travelled in the business cabin which I have to say, rivals many so-called 'First Class' products. The crew were courteous, addressing us by name and nothing was too much trouble."
Cons: "Boarding at Bali Airport is chaotic. This can hardly be attributed to Qatar Airways but this needs to be sorted out. When boarding began, it started with "Group 1" rather than business and other priority customers. It ended up rather chaotic with boarding halted at the end of the escalator causing a very uncomfortable situation as people struggled to get off the escalator."
Pros: "Nothing much."

Then told that we won't be getting on until 7am the next day, but only really started boarding at 8:30am. By the time we were told about the reschedule to the next morning, it was too late to get a hotel room (too far away) and was told that I could use a 'Quiet Lounge' at the airport (which wasn't quiet). While waiting to board at 7am the next day, ground staff told us that they had to change the plane so there would be a further delay. On boarding, we discovered that it was the SAME PLANE."

Pros: "I haven't flown with Qatar for several years, but my memories of an exceptional experience were replicated. Fantastic modern aircraft, brilliant crew and great food."

Pros: "I had my seat changed due to my injured leg, staff acted swiftly, flight was relaxing."
Cons: "They ran out of options on the food and considering it wasn't a full flight that surprised me."
Pros: "For the most part it really was a most excellent flight, especially the Dubai to SF leg where there were SO MANY CHILDREN around [should get a free upgrade just for surviving that] but the flight crew did exceptionally well and remained calm all the way through. Apart from one grumpyish woman on the second flight the majority of crew were exceptional and really went out of their way to serve and help."
Cons: "I slashed my finger fairly painfully on a toilet door while pushing it from the outside to open it on the Dubai to Cape Town flight [again, an upgrade on my home flight which is a bucket list dream would more than make up for that!] which i pointed out to a flight attendant and they took note of it and bandaged me up so it was dealt with well but hopefully that gets sorted out [she said she would write a report] cos it did unfortunately affect the rest of my flight a little... And so many crying babies [thankful for volume control on headphones] but literally that was it - love flying Emirates cos on the whole felt super well treated..."
Cons: "food was average"
Pros: "ICE is amazing, excellent food also in economy, comfortable seats."
Cons: "If you sit on the double seats in the back you have to wait a lot to get off the plane."
Cons: "Child kicking seat from behind for entire flight"
Pros: "The plane left on time, the ride was smooth and journey felt safe throughout its entirety. I enjoyed the flexibility of the seats; the quality of the cutlery, duvet, headphones and the matteress provided. The ICE is a brilliant entertainment system; giving an array of films to watch and games to play. The cabin crew were polite, friendly and helpful, and gave an excellent service as one would expect from travelling business."
Cons: "The interior of the 777-300 was outdated, especially knowing that 777's have gone through an interior overhaul, so I was unfortunate to not be on of those refurbished planes. The food and the Virgin Mojito was not the best as I did expect it to better considering this was a business class. And the ICE tablet and its remote is not the most userfriendly nor responsive to use, as it does get a bit fiddly."
Pros: "the food is excellent"
Cons: "If you want upgrade you should bay 2100 USD why it’s a upgrade not new ticket !!"
Pros: "As above"
Pros: "Very efficient. Fab selection of movies."

Cons: "Nothing as such."
Pros: "Crew professionalism, Entertainment Flight timing Take off and landings"

Cons: "We were told luggage to be collected at vasco de gama. It was unloaded at Bangalore. We then had 13 hours stuck in the airport with our luggage. Had our luggage not been unloaded, as expected, we would have a bit more freedom to move about. My luggage tickets had come off so I had to re-check in in. They then gave me the wrong labels saying i had to check in at internationals. This caused terrible chaos and they did not seem to understand when I tried to explain that going from Bangalore to vasco de gama was domestic. Other than that a pleasant journey."
Cons: "There is a lot of difference between flights experience from San Francisco to Delhi and Delhi, India to San Francisco. India to San Francisco was little better. Service was very poor. Food was not on time and quality and quantity was poor. Get your own stuff to save yourself from starving."

Pros: "As I boarded Air India New Delhi to San Francisco, I felt it like a "senior citizen " flight. Most of my time went into connecting with elderly people around. Most of them were first time travelers. Curious ,anxious , innocent and slow learners ; I enjoyed helping them out with tinny tiny tech bits. The collection of Indian music , movies was good to , suiting to Indian taste ! And the food was good !"
Cons: "Boarding the Air India New Delhi to San Francisco was one of the most adventurous experience for me! The Mumbai - New Delhi journey was short and sweet ! As the connecting time was around 2 hrs , I had to rush to board the next flight. The connecting bus to the airport made me wait for a long time and I reached the gate quite late after the boarding was over! And after all this drama where I rushed and ran through ,crossing the domestic airport ; there was a long queue for general security check. I ran to the immigration , rushed through the security check. And finally reached the gate. I forgot , I am pregnant ! I was told there , I will have to shift to another seat due to "emergency" exchange reason ! Oh gosh ! I felt , I deserve a round of applause for making it there and I was offered an exchange ! It's unbelievable, but the flight got delayed by 3 hours! Yes, you read it right , by three hours ! The crew members were not that prompt and welcoming ! The flight toilets weren't sufficiently equipped with the necessities. They was no hot water flowing through many taps, seat-covers were missing, even the basic toiletries were."
Cons: "Entertainment systemwas not working through out the flight"
Cons: "They were skimpy on giving food. For 2 adults and two paid kids, they were trying to get away with 2 peanut pouches! Requested special kids meal, did not receive it. Crew could not help with frozen screen, so over 15 hours no entertainment"
Cons: "Overhead reading light and TV display were broken rendering me without entertainment for 16 hours. I couldn't event charge my electronics to use them as a flashlight to read my books as the USB chargers were broken for the whole row. I couldn't even get the attendant's attention for a while since the attendant call-button was broken. By the time she walked by next (hours later) she restarted it but it didn't fix the issue and I had no way of getting her attention again for a while. Really awful experience."
Cons: "Food was cold"
Cons: "Horrible ....very poor in flight services. Outdated aircraft untrained crew .worse in flight experience I ever had .i will never ever fly again with air India .if you are thinking about booking with air India please don't. they will be named worst airlines in the world . I recently fly with air India from san francisco to delhi and back and I regret my decision .unfriendly crew and food quality is very poor they only served beverage one time in 16 hours flight. So learn from my mistake do not book with air India."

Pros: "That I got to Muscat in one piece."

The plane looks and smells old, the staff is clueless about most things (even what they are serving for dinner!). Over all lack luster experience, surely not putting myself thru an Air India experience again."
Cons: "The screen was not working which is so bad I have been paid so much n travelled"
