Pros: "Good"

Pros: "Amazing experience. Pinnacle of customer service"

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: "Staff were fantastic."
Cons: "Better movies please."

Pros: "Seats are great!"
Cons: "The food options were not that good this time."

Pros: "Not-so-full flight meant we could move about and choose more comfortable seats."
Cons: "TV unit didn’t work, lucky me. They tried two times to restart and reboot but to no avail. The attendant said my choices were to not watch or move to an empty seat. I chose to sit next to my wife."

Pros: "Crew is so helping and attentive , not like american or european carriers . A350 was one of the best planes Inflight dining options in economy was like premium economy Entertainment system was too good"

Pros: "Confort"
Cons: "Same as above."

Cons: "too hot called groups too fast for boarding"

Cons: "My entertainment unit on the Perth Doha leg never worked even after several resets"

Pros: "Nothing about American Airlines Never ever to travel with it again"
Cons: "Passengers service bad Air hostesses just rude I Don’t even know why someone wants to work When they can’t even smile There were few seats were empty but they were offered to fellow passengers who happens to be different colors Person Then me America airline lost my family business for ever"

Cons: "They claimed they have free WiFi, but this is not true. Passengers has to pay if they want access to WiFi. Uncomfortable sitting and you cannot adjust it to a comfortable level. Crew keeps demanding sit need to be upright."

Pros: "price, comfort, food"

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."
Cons: "Only one minor gripe, the passengers seated behind me talked incessantly, making my attempts to sleep impossible. I asked if there were any ear plugs available, but none could be found. My own fault, I should have packed my own."

Cons: "Flight planned to leave 30 mins earlier and didn’t send any email or informed me."

Pros: "The airplane seats in economy were comfortable for the very long flights I took with Qatar Airlines. The seats had enough room between the back of the other seat. The seat reclined to a comfortable position. The seat back provided a built in head rest. The TV's in the seats were the largest I have ever seen on a flight in economy. The staff were helpful and great. The food and drinks provided were decent!"

Cons: "Bad app don’t trust"

Pros: "Crew were great and sincere"
Cons: "Qatar gave problems changing flight for emergency purpose and had produced all documents but they wanted further documentation which could not have access because at,a foreign country. Felt they don't care and it was all to do with money which had to pay."

Cons: "- Leg Space is challenge"

Pros: "Food was great Seats were comfortable Everyone was super nice"

Pros: "Flight crew was quick to provide food and drinks but quality of the food was not as good as Emirates."
Cons: "-carry-on did not fit on center overhead compartment unless I put it side ways, which then takes up space for other passengers. Same carry-on suitcase fit nicely on Emirates airplanes. Basically, carry-on overhead compartments have been made smaller on purpose or by engineering error, and this makes me not want to fly Qatar airlines again. Less food options. I went to the Gally and they only had kitkat bars for food. Emirates offer fruit, sandwiches, and many choices at ALL TIMES of the flight for economy class."

Pros: "On general quite good"
Cons: "Checking in, issuing boarding passs was very slow. Maybe it has nothing to do with QA."

Pros: "Great service, on-time flights, very comfortable planes in excellent condition. Great value for flight cost, BOS-KTM, through DOH. I would fly again with them."
Cons: "Lots of mediocre movies to select from. Very slow deboarding in Doha onto buses."

Pros: "timeliness"
Cons: "food"

Pros: "Everything"
Cons: "nothing"

Cons: "The online check in system was down so we all had to line up to check in."

Pros: "Cramped"

Pros: "Excellent crew who were warm and attentive. Wide range of entertainment options."
Cons: "Food was disappointing. No western option despite it being a London bound flight."

Pros: "Some how it was a good experience"

Pros: "Qatar is quite possibly the best airline in the world, especially on its long haul flights. It is heads above the other two major Persian Gulf airlines. All the employees with whom I dealt were excellent and customer-oriented. The planes between Doha and London were new, had more space than older planes and had an excellent selection of movies and TV shows. I ordered special meals on all the flights, and I was very satisfied. I have been a fan of Qatar Airways since I flew it to Australia in 2011. It continues to do a superb job, even in Economy."

Pros: "I liked the schedule was on time and smooth plane ride."
Cons: "I did not like the room in the plane. The seats where to close and u I couldn't sit back because person behind u would complain. Flight attendants did not really going around to see if we were good r needed drinks or even smiled they looked very upset and had some attitude when I did ask for something. Customer service needs more improvement."

Pros: "Another B787. Had empty seats next to me."
Cons: "No menus handed out by the crew and little explanation of what the meal was beyond beef and rice or chicken and potato. For some reason they only serve a snack instead of a second meal on this flight."

Pros: "Incredible staff, fast boarding, great entertainment center."
Cons: "Breakfast frittata was like rubber."

Cons: "Not enough check in desks operating - very long wait"

Pros: "Decent leg room. New plane."
Cons: "Only one meal was served in about a 6 hour flight. By the end of the flight I was famished."

Cons: "Check in crew in Lahore ganged up against me and wanted to extort £200 for taking me laptop on board along with my hand carry. No where in the world has an airline ever asked me for this, and I fly a fair bit. Since I didn't allow them to extort me, they forced me to throw away my brand new Delsey hand carry at the airport. I had no cover as they threatened to if load my luggage and not let me fly home. Not a 5 start airline from any angle. Will never use Qatar again!!! This was my first and last flight with them."

Cons: "Check in crew in Lahore ganged up against me and wanted to extort £200 for taking me laptop on board along with my hand carry.

I had no cover as they threatened to if load my luggage and not let me fly home. Not a 5 start airline from any angle. Will never use Qatar again!!! This was my first and last flight with them."

Cons: "There is nowhere in the airport to go for long layovers. The ticket counter didn't open until closer to the flight, without it I couldn't get inside to the Travelers Lounge, and spent most of my time in the entry area. I also was assigned a middle seat, which is even less fun than usual when you've been in India and your bowels are acting wonky."

Pros: "New airplane. Friendly air hostesses and top notch service.. British Airways can say goodbye to my money"
Cons: "Nothing"

Pros: "No problems at all!"

Cons: "Food is not up to the standard. They make announcements that there will be snacks like sandwiches and ice creams, but they don't offer that openly. You have to ask for snacks. Now we, US citizens don't like to ask for food just so you know. The crew should offer. if we don't need the food, we can always say no."

Cons: "Worst customer service"

Pros: "boarding was okay"
Cons: "BA operated flight. cannot compete with Qatar Airways, even if the ticket is a Qatar ticket."

Pros: "The chairs was comfortable and crew was nice"
Cons: "Again food option all the time is spicy."

Cons: "There were no fans or AC running before takeoff and we had to sit in a hot plane for an hour. My seat wouldn't stay reclined. My child's entertainment system froze early on and no one fixed it. One of the toilet seats was broken. Airport checkin lines were very poorly managed."

Pros: "The crew was very nice, but I did not require a lot of attention."

Cons: "Proper meal for lunch but for dinner we were given snack foods (croissant, fruit salad and chocolate cake). Also my bag got left in Delhi as I had a fast transfer - Got it back but it was quite stressful!"

Cons: "Working entertaining systems"

Pros: "Arrived early . Really rude air hostess told me to go and sit down .I was standing because my feet were swollen .So rude ."
Cons: "On the ay out broken seat no TVs no choice of food poor service . Return better seat , vegetarian option was potatoes curry with rice ,fruit with ? A bug in it ( yet to go under microscope ) and a rice based desert !! Poor choice of films . No service between meals unless you went and asked for"

Cons: "The crew certailny could be more cheeful Perhaps they just were tired. The food was terrible despite the airline from nation of exqisite cuisine. The enternainment screens did not respond or work even with the remote. There should be better maintainance."

Cons: "Seats, leg space."

Cons: "Seats and surroundings could be cleaner."

Pros: "Nothing in particular"
Cons: "The cabin was freezing. People were wearing jackets, hoodies, scarves and hats but the flight attendants didn't do anything about that. The disastrous Rayanair at least realised how that was making them burn more fuel and now they are letting passengers melt with heat. When will Air India learn this?"

Pros: "The flight went very smoothly. We left the gate 10 minutes ahead of schedule, and landed early. The crew was very good. Landing was perfect."

Pros: "The 787 DL was a spectacular ship and lerf ct for a sub 6 hr crossing from Newark to London"
Cons: "passenger trying to load were stressed and unorganized. But circumstances were unusual with Primera going bankrupt hours before and causing busy flight."

Pros: "Good. I like it."

Pros: "good food and support for wheelchair but have to wait longer then expected"

Pros: "The crew were very friendly and helpful. I paid $25 extra (which isn't much at all) for an exit row and it was as comfortable as it could have been in economy. I got to my destination safely and on time which is most important."
Cons: "I wasn't able to keep the screen for the entertainment system up (I had no seats in front of me so the screen was on an arm) so I could not use the entertainment system. If I had been able to use it, I usually prefer using the audio part of the system and I noticed that only Indian music was available. It would be nice if some western music was also offered."

Pros: "i have never flown before so i was very surprise that all the staff was very good and very helpful. i have told my family and friend what a good Experience i had"

Pros: "Overall it wasn’t that bad"
Cons: "My entertainment set was broken so I was suffering for 15 hours"

Pros: "Pilot was perfect"
Cons: "Food should be good"

Cons: "I was in the check in desk two hours before the flight time. I was asked to go for baggage scanning twice and that took almost hour and half. We had to rush with the kids and didn't get any assistance from the air India ground staff."

Cons: "The food"

Pros: "Onward journey was good, except for issues with the entertainment system in out sears."
Cons: "other than taht things were comparable to other long haul trips. excepted some snacks to be served in between the 13 plus hrs trip"

Pros: "I liked nothing. Starting from bagage transfer from SpiceJet in Delhi"
Cons: "Behavior of customer service in Delhi Airport. Absolutely unethical behavior from an agent called Vikash who claimed to be a manager in transfer disk in Delhi."

Pros: "Boarded fast; on time"
Cons: "Seat did not recline; food poor quality"

Cons: "Food not good at all"

Pros: "Aircraft comfortable Crew helpful"
Cons: "Flight delay not announced till queuing up for boarding Text from Air India to arrive 4 hrs before boarding Flight delayed by 1.5 hrs due to fog but no intimation till after queuing at gate! No announcements re extent of delay. Crew got on with doing their job Lack of info - ? Down to Delhi Airport but distinct lack of Air India ground support But in their defence all flights were Delayed maybe this was just one of those things but to not let passengers know - this could do with improvement."

Pros: "Everything was smooth sailing and even landed 45 minutes early into London. Service was good and no complaints."
Cons: "Not a huge selection of movies in the in-flight entertainment but enough to get through the flight!"

Pros: "1. Good food. 2. Air hosts and hostesses were excellent. 3. The baggage handling was good. No damage or loss. 4. No delay, quite punctual all throughout. 5. Boarding was a little messy, mainly due to impatient Indian passengers who won't let other fellow passengers board without a fight for no reason."
Cons: "1. While checking, the front desk person was absolutely miserable. We had a couple of baggage with 25 kilos and others less than 23 kilos. However, she would not let out baggage go until we evenly distribute all of them and make them all less than 24 kilos. We had to open all our bags and suitcases in the airport and redistribute. Quite a nightmare. So for future passengers, if you get someone like her good luck. 2. The Boeing-777 cargo is pretty old. So though it has everything still there is a touch of shabbiness all over the plane. They are not comparable to the top of the line Dreamliners that AI runs quite a bit. 3. Though the entertainment system was good, however, some of the remotes or audio outputs were not working well. Like my audio output was not functional at all. I changed the headphone and it still did not work. They suggested to use my own audio bud, however, I did not have one. 3. Limited beverage choice."

Cons: "Food was very bad"

Pros: "- Good time of day to fly (left midnight, arrived in London around noon) - the flight coincided with normal sleep time, so I arrived with very little jetlag. The aircraft (Boeing 787 Dreamliner) was well equipped, had ample luggage space and effective mood lighting. - Flight left on time and arrived early."
Cons: "The aircraft could have been cleaned better."

Pros: "- Leg room in emergency exit seat (pre-booked and paid for) - Overall service - On-time departure - Far improved customer service levels"
Cons: "- IFE is poor, very limited selection (in English at least) - multiple document checks every time I moved! Approx 6 people needed to see my boarding pass before I got on the flight...."

Pros: "Beautiful new airplane with super friendly crew. I was catered to constantly. This with the fast pass to get through customs in under 5 min was wonderful. Highly highly reccomend."
Cons: "Selection of movies for English speaking customers very limited compared to rivals."

Pros: "Plane staff were very nice. Food & red wine were both very comfy. Loved that they supplied pillows & a nice blanket! The top halves of the seats were very comfy – the same cannot be said for the bottom."
Cons: "Was upsetting that the entertainment consoles did not work for virtually all of the flight, and even when they were the content that I wanted to watch 'could not be loaded' for some reason."

Pros: "The entertainment was pretty good. Megar selection, but good quaility. The flight was on time. The leg room was pretty good and the seats reclined back far."
Cons: "-food was poor: too spicy, stale bread. Breakfast was also stale. -the flight attendant ignored my call button request, even cancelled it twice before coming over. Then rolled his eyes at my request for a pillow. -They fumigated the cabin. I'm not kidding. They popped these aerosol canisters and walked around the cabin. I have no idea why. The flight was from NYC to London Heathrow. This was unpleasant to say the least. -since it's a cheap airline, the clientele was as to be expected. Some guy jumped in the lavatory in front of me after I waited 20 mins. The boarding process was like the line for the lifeboats on the titanic. -they played some traditional Indian music during landing. I understand it's AirIndia, but if I wanted music playing I'd have put it on myself. It seemed intrusive and strange. -they "misplaced" our luggage. It didn't come out of the carousel. Bags claim said it's "somewhere in the airport". Myself and about 30 people waited 40 mins for them to find our bags. At least they didn't go with the connecting flight to India? -we deplaned on the tarmac and took buses to the terminal. Once there, AirIndia staff asked us to produce our bording passes again. One women said she threw hers away, since we were already off the plane. They yelled at her saying it made "it" easier for them to process. I have no idea why they needed to see them once we were at our destination."

Pros: "The price and AI staff attitude/demeanor were both very good."
Cons: "The actual service quality was below the average US flagship airline, far below the average EU flagship airline, and very far below the average Asian flagship airline."

Pros: "- The crew was pretty good. Helpful overall"
Cons: "- The boarding was handled very badly. Couldn't believe my eyes to see something as simple as boarding looking like a complicated job! - AI crew is pretty rude when it comes to helping with overhead cabins: The cabins are high and it really is very difficult for most individuals to manage it single-handedly. For crew to say this is to any passenger,"You opened it. Now close it" without a 'please can you close it' just sounds atrocious and mean"

Pros: "Hot breakfast, with hot beverages, very filling and satisfying."
Cons: "Only vegetarian meals, dirty cabin with grubby overhead panel."

Pros: "The window seat"
Cons: "Bathroom a mess"

Cons: "Seats leg room & punctuality"

Pros: "On time, good movies and overall o What one expects for an economy class flight."
Cons: "Sometimes the air hostes were hard to understand."

Pros: "The plane given in the flight, Dreamliner 787. Food and service, everything was beyond what we expect in domestic flights. Recommended a thousand times over other domestic Indian airlines"

Cons: "Not helpful at all"

Pros: "Flight experience was overall very good..Everything went smoothly.....food was OK...had seats in H row and these were very comfortable...could sleep for 6 hrs..In flight entertainmemnt was fine..But didn't require much of it...as I slept through most of the flight...above my expectations...4.5/5"
Cons: "Crew behaviour could have been better"

Pros: "Nothing"
Cons: "So dirty! Absolutely filthy. Here was human feces all over all of the bathrooms! It was a very long very dirty very smelt flight. I would never fly air India again!"

Cons: "The airplane vibrated strongly upon take off and landing making me question its flight worthiness. The service was unusually bad, the air hostess who served me had a very abrupt manner."

Pros: "1 hour check in at Kolkata to Delhi, at first wanted us to recheck bags at Delhi. Finally, bags checked through, but needed to get boarding passes in Delhi. In Delhi, 80 minutes at the desk before boarding passes. They suggested we didn't have return tickets, and kept asking for more information. And this was at business class desk! Finally took 4 of them at the desk to take care of it, and then we were so late couldn't get seats we wanted. Unbelievably bad! Beware!"

Pros: "Flight was on time. Boarding was not managed well by Ahmedabad Airport. Two toilets had faults. Faulty tap and toilet seat. Lacking choice in in-flight entertainment despite high quality system. Air India should offer free water at the seat every 2 hours instead it's a help yourself service which is less good. No wi-fi services."

Pros: "Crew were very nice. Food was good. Bathroom stank."

Pros: "I liked the movies offered. The food was stale. The bathrooms were not clean. They charged 100$ for 2lb over weight of 1 bag, and additionally they insisted us to check in the diaper bag for a fee of 100$ more. This is not the way you make money. This is a family unfriendly Airline. They told me that since you are already getting the priviledge of checkkng in a stroller, you got to pay 100$ for the excess 2 pounds. But all airlines allow strollers to be checked in for free.. how does that determine the luggage restrictionfor us?"

Pros: "Nothing at all!"
Cons: "your flight is grossly neglected and pathetically maintained. In-Flight service is probably the worst in the industry. STOP SHOWING ATTITUDE THAT YOU ARE DOING A FAVOR BY FLYING US. My personal opinion give the operation back to the founding company TATA GROUP."

Pros: "Nothing"
Cons: "Don't count on making meetings and connections if your taking Air India"
