"It’s good, thanks for all team members"

"Right now everything good"

"My TV screen was freezing, it was hard to navigate. Everything else was just excellent."

Pros: "The crew was amazing. very helpful and great services."
Cons: "While waiting in the check-in line, it would be better if one of the crew would come and ask the travellers if they have got everything. cause I had my Covid test and it was negative. However, they said that my final destination place won't accept my test. rather me waiting on the line that was not moving ahead at all, I could have sort things out some way. So, it would be nice if the crew would come to the passenger on the line just to make sure they have everything right."

Pros: "Crew was receptive"
Cons: "Food boarding"

Pros: "Crew was amazing"

Pros: "Good flight"

Pros: "Everything- leg space, crew were great, relaxed atmosphere, great entertainment systems"
Cons: "Nothing"

Pros: "Everything."

Cons: "As with all economy seating...it is cramped"

Pros: "The crew was very cheerful and helpful even though I was puking my guts out on a long flight with a lot of turbulence"
Cons: "It was an insanely long and pukey flight. The airsick bags have this seal that you have to tear off before you can open it which my son discovered a little too late."

Pros: "Great service & very comfortable lie flat business class seat for this red eye flight."

Cons: "Good job keep it up"

Pros: "Nothing amazing. Everything was okay and average."
Cons: "They weighed carry on baggage and made me pay extra. No other airline does that. The check in crew at LAX were not friendly at all. No hot towel service after boarding. Food served was very small portion, not enough. Only 2 meal service during 16 hour flight. Not enough beverage service in between."

Cons: "Qatar airways claims to have inflight wifi. But it is not true because it did not work in either of my flights. Food could have been better."

Pros: "Good service and a modern airplane"
Cons: "The check in at JFK, too chaotic"

Pros: "More leg room, easy boarding and comfortable flight in economy"
Cons: "NA"

Pros: "The layover was hell. They put me in a warehouse with wooden benches for beds. Never again"
Cons: "Horrible service. The US part of the journey was fine but the rest was aweful."

Pros: "The friendly and helpful service."
Cons: "There was a long line by my seat to use the restrooms."

Pros: "Food , good accommodation, friendly treat!"
Cons: "No thing really!"

Pros: "Ground crew was especially helpful to my mother who could not speak English or Arabic, and had never flown before. She also had difficulty walking, so everyone assisted her in the airport and during her long connection in Doha."

Pros: "Q-suits. Very comfortable and private. Great upgrade to the 777. WiFi now available for very reasonable price"
Cons: "Bus transfer to Termial 5 is VERY poorly organized and takes over an hour. This makes it harder to get to Terminal 5 even if you don't have to clear security again. Seats had a bar under the padding at about the position of my hips. Uncomfortable to sleep for several hours"

Pros: "The food and the crew were excellent. Highly recommend the chicken massals"
Cons: "The seats in economy class were a little too close for comfort"

Pros: "The staff are great, the food is good."
Cons: "The seats are awful, especially on the 7 hour flight from Doha to Barcelona. Very narrow, marginal recline. Also the flight was very hot, my watch thermometer said 33° at one point"

Pros: "everything"
Cons: "Nothing"

Pros: "Great Staff"
Cons: "Asian Vegetarian meals needs some improvement. Lack of Africans as part of the crew."

Pros: "Crew"
Cons: "Preboarding area had no bathrooms. Boarding process was erratic with conflicting calls for zones. Discomfort with people bumping you as they walked down the aisle..toilets unkempt. Exit row USB port misaligned with seating area, so my USB cable bent and broke."

Cons: "The website is not easy to navigate."

Pros: "I love this app , it's awesome it's save my money and time"

Pros: "Very comfortable flight and crew"
Cons: "The plain was very old."

Pros: "A new Dreamliner. Nice! Very good service. Gate personnel were very accommodating. Nice smooth flight. Doha airport was nice and mostly empty. Mediocre selection of restaurants."

Pros: "Very kind & friendly crew. Boarding was smooth & flight was comfortable. Food was good considering it's airline food."

Pros: "Staff were professional, food was good and seats were comfortable."

Cons: "The passenger sitting next to me was really sick due to flu. When i explained the situation and asked for masks to the attendant, you guys did not have even one. I was disappointed with that. I think the flight should have some for these kinds of situation so that other passengers can protect themselves. Thanks."

Pros: "Much better than the flight from Mumbai to Doha. The crew was attentive."
Cons: "Meals could have been better. The good didn't compare to business class on other airlines."

Pros: "Service of air stewards very friendly and polite"
Cons: "This goes for Qatarfigjta from harare to Doha and Doha to Washington DC and back. I am not going to give individual report on each one. Food - my daughter could barely eat anything and the vegetarian meals were stone cold most of time. It was hard to eat at Qatar airport because not only is the food terrible (Burger King and bad Asian food) but outrageously expensive. Our media system did not work for one leg. ** way to many ads on your media system. Every time you watch a new TV episode, you have to sit through 5-6 ads for stuff that is not interesting and the same each time. ** plane info on media system keeps reverting to Arabic even when English is indicated as preferred la gauge. We had to place our iPads in checked luggage for flights from harare to USA as we went through Qatar. *** I asked for quiet seats and was given seats near kitchen and toilet even though I booked in hours in advance. One leg had my ten year old daughter and I in different rows even though I checked in 4-5 hours in advance Of flight . ** staff moved my hand luggage without my permission and without informing me - it was stressful trying to find it."

Pros: "On board crew are excellent."
Cons: "Ground staff requires training specifically on communication related to boarding. Travelers were confused as to what zone is boarding at a given time as there were no announcements. Pathetic boarding process."

Pros: "Checkin was really quick, needed to have some facilities for the passengers who have more than 8hrs layover."
Cons: "The crew was not efficient or always looking for shortcut. The specific person assigned never recommended or gave any information about the amenities available rather was waiting to be asked uneasily and was not polite at all. Need to be trained more effectively for such a 5 star airlines."

Pros: "Good legroom with respect to others airlines.. the plane is clean.. multiple bathroom so no long waits Dinner was tasty.. however the breakfast was not."
Cons: "Cheap headphones will not isolate sound from airplane engine for such an expensive entertainment"

Pros: "The crew were so nice. But flights are very long, and coach is incredibly crowded & uncomfortable. Beverage service is frequent and generous with a good variety of fruit juices, soft drinks, red or white wine, etc."
Cons: "Using the video screen is a mystery tour - badly programmed. The Doha airport is an architect's Ego Trip and badly laid out, extremely long walks to get anywhere, ferocious prices for anything (carry snacks for your layover!). The smoking lounge doesn't even have a proper exhaust system so smoke permeates the terminal in the vicinity. Plus 4 bar stools hogged by rude, arrogant young Arab men who have NO respect or consideration for elders, disabled, etc. Incident with boarding passenger in Saigon was VERY badly handled & delayed departure over an hour, risking connections for a number of passengers. They cannot handle things well, yet crew is basically nice, kind. Food is AWFUL; saving grace is fresh fruit, roll & butter, yoghurt - the nice little side dishes."

Pros: "High quality gluten free meals (best I've had on Qatar Airways)."
Cons: "Seating needs to be more spacious."

Pros: "Excellent service and aircraft! Top tier entertainment and food and wine."
Cons: "NADA!"

Pros: "Liked the raw vegetarian meal as it was perfectly plain. Attendants also very solicitous and went up and down several times with water after the meal."
Cons: "Seats are small and huge line for the toilet, but that is the nature of the plane and not Qatar's problem. Boarding was only good because passengers did not cooperate adn stood up when they were asked repeatedly not to."

Pros: "Everything is fine and have a wonderful time"

Pros: "Very comfortable, great staff, entertainment options were huge! New aircrafts with comfort in mind."

Pros: "The crew on the flight was excellent. They'll bring you pretty much anything reasonable you ask for. In flight entertainment options were many. I don't eat a lot of airline food, but the meals exceeded my expectations."
Cons: "I am quite tall (6'5"/1.92m), the in flight comfort was brutal. It'll take my knees a week or two to forget the constant jamming from the seat in front of me. Otherwise, on boarding was well organized, but very slow. Sound quality on provided headphones was very poor."

Pros: "Good staff and service"
Cons: "Require more leg room"

Pros: "Very nice service"

Pros: "movies were good."
Cons: "14hour flight and you cannot give terrible food. You should know that. Although, a crew member did give extra food i request for a thing I liked."
