Cons: "Under 2 babies did not get enough milk They should have baby food items cereals, crackers or baby foods options"

Cons: "Seats for its along way"

Pros: "The crew was excellent. The seat was reasonably comfortable. Boarding process was very orderly and smooth."

Pros: "seats were awesome, so as the food and the occasional snacks were delightful"
Cons: "My entertainment screen wasn't working, but since I got a window seat I didn't complain. Long time for a 12 h flight without video or something to occupy myself, but at least the USB port was working..."

Pros: "Everything! It just awesome"
Cons: "Nothing can be better, an awesome flight"

Pros: "aircraft A350 , food choices , Doha airport , Staff attitude and willingness to help ."

Cons: "Crew members are waking up for lunch and breakfast but not for snacks and other beverages. We are feeling hungry later. we aren't knowing when they ll provide."

Pros: "The crew were fab"

Pros: "Customer service"
Cons: "Food"

Pros: "Good service"
Cons: "Food"

Cons: "Will fly in a bit.still in Qatar airport waiting for my flight"

Pros: "The crew was attentive and polite. The flights were on time, and the entertainment options were good. The Doha airport is quite nice, with many eating and retail options. although everything is very expensive, even by airport standards."
Cons: "My wife and I personally don't mind a selection that leans heavily toward Indian food, but I imagine others will not. The main courses were mediocre and the "sandwich" offered between meals on the 13+ hour flight was cold, soggy and inedible. The seats on our A350 were hard and not very comfortable, and the recline function was difficult to operate. Security at the Doha airport was confusing. We had to go through 3 separate checkpoints for our transfer, each with different rules and procedures. The final check at our departure gate was the worst, with impatient officials giving hurried instructions in heavily-accented English, and scolding if passengers didn't understand. I was sent back through a second time to remove my camera from the bag (and to be scolded by the agent), and was patted down a second time coming back through the x-ray, which had green-lighted me both times. It made me wonder if this was a reaction to the extra scrutiny that Arab passengers receive from our airport security in the USA."

Pros: "Cabin crew service was very good. Flght with Airbus 350 plane was really comfortable and quite. They put extra care for kids and babies and all of kids get gift bag with toys, chocolate etc. which makes everyone happy Especially kids. I personally like to watch new release movies and enjoyed to pass my flight time."
Cons: "Their south indian food was testless in both inbound and outbound flight from Philadelphia to doha. Snacks was good but meal definitely they should have better to change it."

Pros: "Qatar beats every US based airline, hands down! The planes are clean and modern with better seats, leg room, technology, food and staff. Everything is included in the cost of a ticket, something that US airlines should learn! I cannot say enough about the experience and wood recommend to anyone traveling to destinations served by this airline."
Cons: "I cannot think of a single thing."

Pros: "Entertainment system good,"
Cons: "Boarding was late, seating very cramped."

Cons: "Small chairs"

Pros: "crew was lovely and plane was very new"
Cons: "food quality is not very good: sometimes it was hard to see what it actually was and it tasted like that too. headrest in the new plane is not comfortable at all as it is rigid and can only be moved up and down."

Pros: "The service on board is excellent"
Cons: "Nothing"

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."

Pros: "Incredibly attentive service"
Cons: "Internet service didn’t work. Also waiting for can refund because of unannounced 12 hour delay on the outbound flight."

Pros: "Had the best flight experience of my life. Comfort, food & especially service was excellent."

Pros: "Same"
Cons: "I understand it's the industry standard, but seats are too narrow with shared armrests."

Pros: "The crew was friendly"
Cons: "The security process to board the plane had no order. Stood in line while people after me was able to board the plane. When it was my turn, I was randomly selected for additional security screening."

Pros: "The crew was excellent in their mannerisms, efficiency, service and never ending smiles."
Cons: "The flight was not overly crowded and many of the passengers were seated with three people per set of seats while others were seated individually and able to spread out with much more comfort. I felt that when the flight crew saw this they could have made everyone much more comfortable by switching people to two people per row thus giving them more room especially on such a long flight."

Pros: "food was decent and the staff on the plane were pleasant."
Cons: "Qatar airlines blatantly lied to me on several occasions and treated me like I was dirt. They lost my baggage and re assigned my seat several times each time pushing me further back into the plane and eventually putting me into a crowded row when the plane was virtually empty."

Pros: "Flight was not crowded, room to stretch out. Food and service was good."
Cons: "Difficult boarding procedure."

Cons: "- The Flight was canceled to fly directly from DOH to PHL.... Our party was put on a transfer at ORD...added additional 8 hours of layover... flight itself wasn't terrible... but the bathroom situation could be hectic..."

Pros: "Again, the flight attendants were so sweet and nice and hospitable."
Cons: "The sitting quarters were so cramped. Maybe next time I'll save an additional $500 to go up a class but it was so smashed. It did not leave room for me to use the desk to eat or use my laptop."

Pros: "Shared a row with three seats with another person, middle seat was free! New entertaiment screens."
Cons: "Food was average to less."

Pros: "The head flight attendant in the economy cabin was nice, after a bit."
Cons: "My entertainment system stopped working and all they could offer me was something farther back in the cabin. As a Gold privilege member, I choose to sit at the front of the cabin, and yet the entertainment system was unavailable. I wish Qatar Airways could compensate me for my unfavorable experience."

Pros: "Flights out of and to Philadelphia cuts out the whole traveling to and from NY or DC. This is a big plus for me since I live in Delaware."

Pros: "Kept my Insulated tea mug filled with hot water."
Cons: "Plane left 1 hr late. Crew tried to make me check my carry on because it was a "full" flight and even though my medication was in it and I did not have a lock. Baggage handling bent my pull up handle - it no longer works - suit ace was brand new."

Pros: "Pleasant and professional crew on a new and well kept plane. The food and entertainment options were both varied and enjoyable. Big plus was the care package on a transoceanic flight. It only cost them pennies but it was nice to have a mini toothbrush and toothpaste on a 14 hour trip."

Pros: "Fast and easy to board nice crew worked fast and smooth large proposal for entertainment"
Cons: "more diversity of beverage offered Also please propose coffee or tea before/after dinner and breakfast, nobody proposed me and I thought it would come later but nothing came. I should have asked before the end of the service but I was surprised it wasn't coming automatically."

Pros: "The food was amazing, and the cabin crews were all very nice people. I would love to use Cathay Pacific in my next trip. Also, I loved that they provide a lot of diverse movies from all over the world, along with good music lists."
Cons: "Honestly i think there are not much space for each passenger."

Pros: "Airport checkin crew sucked, in-flight crew were fantastic!!"
Cons: "They made me check my carry on for a flight that was MAYBE 50% full... ANd If the ground handlers were actually awake when we landed in Vancouver... took 43 minutes for the first 5 bags to come out.... and another 7 minutes before anymore... WTAF!??"

Pros: "Entertainment was OK, but no wi fi offered."
Cons: "I AM FURIOUS VOYAMA SPELLED MY NAME WRONG 'RUSSELLG" CONNECTED AS ONE WORD RATHER THAN "RUSSELL G EWALD." WHEN I FOUND THIS OUT A DAY AND A HALF BEFORE MY FLIGHT, THEY REFUSED SAID NO CHANGE CAN BE MADE LESS THAN 48 HOURS IN ADVANCE. I WROTE FOR RETURN FLIGHT WEEK IN ADVANCE AND WON'T CHANGE IT"

Cons: "The self service check in and baggage drop at Brisbane was not effective, requiring a lot of staff intervention and help"

Cons: "Cancelation process was too poor customer service was also too poor. And high cancellation fee. Customer service representatives did not tell me when I am going get the money back and also weather my ticket is also canceled or not."

Cons: "Didn’t like the seating arrangement. The check in counter was unwilling to accommodate us, even when we tried to check in four and half hours prior departure. We were unable to seat together for the long flight. On the plane, I noticed 2 family members travel together got aisle seat. I was really disappointed that Cathy Pacific allowed passengers pre-select seat in this method and has no authority or unwilling to accommodate others that flight together. Will not flight Cathy Pacific again."

Pros: "Very courteous and helpful with handicapped people like my mom."

Cons: "Upon arrival in Hong Kong, Cathay representatives automatically re-booked my connecting flight to Taipei assuming I would miss the connection. This was not the case. I was able to get to the connecting gate on time. Cathay representatives in Hong Kong were rude and unhelpful in re-issuing my boarding pass for my originally scheduled flight to Taipei."

Pros: "Excellent Entertainment Choices. Wonderful Staff/crew"

Cons: "When we booked we asked for a child's meal and we advised of allergies. However I don't see why we would have to ask as we booked a child's seat and you have to provide the age which she is 4. When onboard from SYD/HKG and HKG/LONDON, NO meal was available for our child except for what everyone else was eating. She is anaphylaxis to shellfish, she was given shrimp!!!!! I am sure if she was given a child's meal she would not have got this. We were then told we have to advise the airline 12 hours before we fly that we want a child's meal. I am sorry but when travelling we should not have to do this and nor have we ever had to do it on any other airline. Poor poor poor!!!!"

Pros: "Happy to have goodnight on the flight. Was scared to fly on such a long flight because I'm a decent sized guy. I was even more afraid when I realized I was out in a middle seat. However, the seats are relatively spacious, even in economy and my knees weren't hitting the back of the seat in front of me. I also appreciated that we could get up to grab water or juice at any time during the flight."
Cons: "Boarding could be more organized."
