Pros: "The food and crew were great"
Cons: "Older plane the tv panels were faded"

Cons: "WC size (too small) and location ( way too close to flight staff and food section)"

Pros: "The Crew was amazing, the Seat a bit better this Time only 3row of 3 Seat"

Pros: "It is so far a cut above the American carriers. There’s no way to compare them, because Qatar Airways is so far superior. The seats are far more comfortable and larger, the amount of legroom is far superior, you have much more personal space, and the craft is cleaner. Flight Attendants are fantastic! They provide excellent personal care, and are there for everything. They are supremely polite and courteous, and bring things in mediately. Very often anticipating your needs. This is what flying used to be like on United and American. But those people have completely forgotten what service is. Qatar is a 5 star airline. United and American, to my view, are 2 star at best."

Pros: "The service of the cabin was great!"
Cons: "The food was not of the quality I would have expected from the expectation created by the airlines marketing. We boarded close to a full hour later than scheduled and the boarding process was very slow."

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

Pros: "On screen entertainment"
Cons: "Food options- they start serving from front when they reach behind of plane food options exhausted pls ask ground catering to provide more non veg food"

Pros: "Helpful Qatar Airways passenger assistant at check-in."
Cons: "Security check chaos. Obnoxious security woman. BHX strict single bag, 7kg cabin baggage"

Cons: "No"

Pros: "In my departure flight, there were many empty seats and the crew let us move to another seat to lay down and sleep. Also the food was very good and there was a great selection of movies."

Cons: "Snack options were a bit limited for such a long flight"

Cons: "The gentleman next to me had broad shoulders, so I spent most of the flight with my body a bit twisted, and eating without being able to move my right arm normally was undesirable. The cabin was kept a bit warm throughout the flight. We had a long wait (30 - 45 minutes after leaving the gate) before takeoff."

Pros: "service, food and cleanness"

Cons: "Flight delay by 4 hours!!"

Pros: "On time and efficient"
Cons: "Food was mediocre in options and taste. Not the most comfortable flight either. The Manila to Doha leg was much less comfortable than the Doha Philly leg."

Cons: "Food was awful and two out of four family members have been sick. One on each flight"

Cons: "The seats were cramped"

Pros: "The service and the food were amazing!"

Pros: "The Plane was good but not updated with new data"
Cons: "Time delays .. old movies... not a good service with food and beverage... no compensation for the waste of time... restrooms werent clean"

Pros: "Courteous, helpful and professional crew members."
Cons: "No internet service on long international flight. Boarding process for business class could be better."

Pros: "Qatar has an amazing service. The staff is impecable, the food is great, they take care of each detail. Business class is superb. They make the bed, give you a complimentary pitada and moisture lotion. Can't be better than that."

Pros: "A comfortable safe flight. Steph was very helpful and nice and kept us updated when there was a delay on the flight. There were no problemsThe food was airline food and I don't really care for it but I don't think there's anything that can be helped about that. :) my face it was processed promptly and my reservation was handled promptly at the information desk ."
Cons: "The food was airline food and I don't really care for it but I don't think there's anything that can be helped about that. :-)"

Cons: "My screen was not working."

Pros: "Aircraft was much better than the flight from US, food was great. The only thing I wished for was more movies."
Cons: "Lack of movies"

Cons: "very upset about fee i was charged for overweight luggage, and the unclear wording on their sites baggage allowance rules."

Pros: "The plane number one is very good but the onther one to cairo is good not like the first"

Pros: "Transit airport lounge allowed owing to gold status"
Cons: "3 hour delay in take off on Riyadh - Doha sector. No food was served while we waited in the plane to take off. There was no definitive time given for take off during the three hour wait in the plane."

Cons: "The boarding was not handled properly. There was a 40 mins delay, keeping in mind it was never mentioned on the screens. When seeking guidance from crew members about the flight's boarding different answers were given at different time. First it was no delay, just the plane getting closer to the gate, later followed by a 10 mins wait that later became over 30 mins. Once we finally made it on the flight, when requesting a beverage the only option given is water or orange juice and if you have any dietary restrictions (even when providing said information to the airline) you will remain without food on the shorter flights."

Pros: "It was a good flight. I'd give it 4 of 5 stars."

Pros: "Nice crew."
Cons: "One economy cabin as packed with people and the other economy cabin had only 1 person per row. Spread people out more so that they aren't really uncomfortable for a 12 hour flight."
