Pros: "Qatar Airways are still flying, in the midst of Coronavirus, unlike their competitors. This is fantastic! Onboard, there was a full service and excellent crew, all through the night, unlike their competitors during the early days of Coronavirus, when I last flew. Thank you. Qatar Airways"
Cons: "The movie selection, although vast, was not great. I resorted to downloaded Netflix on my tablet."

Pros: "Friendly crew and easy boarding"
Cons: "None"

Pros: "The crew, Venyat looking after my aisle was exemplary. He kept note of when I was asleep when the service passed through. Whenever I go to the galley, he would notice and asked if I needed anything. And this is in Economy!"

Cons: "The airline appears to have done away with the courtesy pack, and this was the one time I was travelling without ear plugs!"

Cons: "The flight is too long"

Pros: "The Crew were excellent, friendly, professional and attentative."
Cons: "We checked in seven and a half hours before this flight as we had just flown from Melbourne Australia to Qatar landing that same day at 0435am in the morning with this flight being delayed from 805 am to 12 noon then to find that we had been allocated the last row right at the toilets. Horrible."

Pros: "Good attention from cabin crew and good food"

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: "Comfort"
Cons: "Extra baggage was charged $250 for 1 extra baggage when other airlines change $70. Also on the Qatar Airway site it states that after 3 hours of the flight if seats are available business class upgrade would cost much less and this was not the case. They wanted $2000 for the upgrade."

Cons: "Cabin crew were not very helpful. Food was average at best."

Pros: "great service from flight attendnants."
Cons: "Old aircraft for flight from Doha to Nairobi, no personal entertainment etc."

Pros: "Excellent service from check in to disembarkation. I was surprised at the amount of leg room, as being a 6+ footer it has always previously been an issue, but not with Qatar."
Cons: "Only downside was the lack of the free traveller pack, eye shade and ear plugs, sleep was denied as I could not block out the sound of the very talkative travellers behind me."

Cons: "I requested a special meal but was not given what I wanted. But overall decent food"

Pros: "The personnel are what makes the airline so special. Everyone of them was so nice and so attentive to our needs. Great experience overall."
Cons: "So the seats while comfy are not as nice as the seats now on the reframed United Polaris and Delta and Air France in their newer planes."

Pros: "Seats are comfortable with plenty of leg space. Aircrafts were clean and tidy. Landing and take off were smoothest I have ever experienced."
Cons: "Menu choice was very basic and quantity was also poor. Food quality was below par in terms of taste and presentation. In-flight crew was inefficient and flow. Meal trays laid on meal tables for hours after the passengers finished food. Flight attendants literally responded in over 30 min of call. I pressed special meals online before boarding. However, the flight attendants were not sure. They went back to kitchen to verify that and return with the ordered meal."

Pros: "best airline food ever"
Cons: "for an international carrier, leg room is horribly cramped. singapore airlines and qantas offer better leg room in their economy class seats."

Pros: "Great food, and excellent choice of in-flight entertainment."
Cons: "Nothing!"

Pros: "Everything"

Pros: "Ground Crew was friendly and did adjust my seating."
Cons: "Food quality was average. More choices needed."

Cons: "Boarding this flight consisted of minimal organization on the crews behalf, the Gate's security machines were off, people scattered everywhere with not enough seats to fit everyone. When entering the gate (with security machines turned off keeping in mind everyone has already passed general airport security and is only trying to enter the gate. Staff would direct passengers towards an attempt at creating a boarding queue. Once passing the gate doors and walking towards the queue directed by staff, it seemed to be a normal occurance to have another staff memeber shout at you and redirect you another way. Getting scolded by gate employees and requested to remove all electronics turn them on and being requested to remove most clothing items at the gate while everyone is watching with security machines off while only selecting a few passengers seems to be a regular occurnace in Doha & with Qatar Airways. People standing all around, no queues were initiated by staff, instead staff would push through passengers to get to the front instead of propretly annoucing the boarding through an intercom. No matter how loud staff was screaming their sounds were drowned out by the passengers which turned boarding a full translatlantic flight into a chaotic scene. Once on the flight I noticed the headphones provided were broken, I politely requested a new pair...from 3 different employees...which took over 20 mins to replaced. Qatar Airways prides itself on quality unfortunately as an economy passenger I have yet to experience any of that other than when it comes to good on flight entertainment."

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

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

Pros: "The airline did not give me 2 seats next to each other like I had booked more than 6 months prior to the trip. They refused to give my friend and I the 2 seats I had iriginally paid for and booked so we were stuck in the very last row of the entire plane with no reclining seats and terrible service for over 13 hours . Completely awful and really disappointing"

Pros: "Service was good."
Cons: "Need to provide more variety for vegetarian food. Cannot serve the same food for every meal on a long haul flight. Provide more entertainment options, more episodes of sitcoms, more movie options, more language options."

Pros: "Flight was good. Cabin crew very good. Food good."
Cons: "Qatar Airways check in at Heathrow was a dis-organised shambles. Arrival at Qatar Airport passport control was even worse at 12.45 am. Long queues,very slow to move, police checking passports unbelievably slowly. Retina scanners should speed up the process. Why then take 5 minutes to check each passport? Poor advert for Qatar, after nearly an hour of queuing I would think most passengers wished they had gone somewhere else."

Pros: "The timing was spot on and I had no major issues. The staff was great. They showed that they truly value customer service and were patient"
Cons: "The song selections were somewhat old and should be looked at."

Pros: "Spacious single seat Plenty of handy storage Pajamas provided Quiet cabin Great service Lounge wonderful as ever Not woken until last minute"
Cons: "Boarding a bit haphazard"

Pros: "When I missed my connection in Dohar, I was put up in an excellent hotel with all expenses paid and great food."
Cons: "When I arrived late in Doha because my flight from Heathrow was delayed, it was difficult to find help when I was trying to rush to make it in time for my connecting flight to Haneda."

Cons: "1-one hour delay in departure. Although pilot tries his best to reduce the delay time but still lost our connection flight. it is known that the whole operation is complex but still believe that effective cooperation by flight crew, ground personnel and others could result in a better outcome. the hotel chosen by the office at airport was not satisfactory. Qatar Airways customers deserve better treatment."

Pros: "I miss the flight beacous of the gate agent the don't now what the doing I was coming from Washington to Dubai I just need to transfer my bags to this flight and the say ohh we canot do that it was unprofessional people I'm sorry so I book another flight from Dubai to Baghdad"

Cons: "Quality of food especially the main meal."

Pros: "Nothing"
Cons: "The flight boarded twenty minutes late despite the plane being at the gate early scheduled departure. Baggage took another forty minutes to load. Then they decided there we were overweight (data that should be known before the cargo was loaded) and off loaded two people. Then after another delay they realised that off loading people meant off loading their baggagge, total delay nearly 2 hours The hedset socket on the entertainment system did not work The USB port did not work THey ran out of food after serving three rows, loaded four sandwiches, no wraps and 2 cheese plates for a full evening flight that was over 5 hours in duration including the delays."

Pros: "Good range of entertainment, comfortable seats."
Cons: "Some dinner choices had become unavailable by the time I ordered."

Pros: "The boarding process and its ease"
