My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat.

The flight overall was good. The attendants did a good job except that 1 female had too much fragrance on. The other things that made the flight unpleasant were out of the airlines control.

Terrible experience resolving missed connection after flight was delayed. 3 hour queue at transit desk, not enough staff, no organisation, worst ever flying experience.

The staff was the best I have experienced as a frequent traveller in a long time.

The Achilles heel of the experience with Qatar Airways is the Doha Airport, especially for travellers arriving into Doha and not transiting. This airport suffers from being ambitiously big and the immigration into Qatar being overly time taking. At the end of my particular flight in which my travel was ending in Doha, the plane parked at a very remote terminal, from where it took me 30 minutes to arrive just at the immigration counter, with fast paced walking and the time on a train inside the airport. Then, at the immigration counter it takes up to a minute or more to process each tourist visitor,due to time taking face and finger scanning processes and langugage barriers if there are questions or information to be exchanged verbally with the officers. If several planes have landed at the same time, it is not unusual that one has to wait 45 to 60 minutes in the immigration queue. In short, the frustration of arriving at Doha takes away all positive vibe of the airline, as the airline and the airport are heavily intertwined and are marketed together.

They didn't board by zones and it was a free for all. The 16 hour flight was the most excruciating experience of my life and the seats were TINY... with no leg space and my feet were swollen immediately. The food was so bad it was inedible.

Well organized boarding, efficient and on time. Nice crew on the plane. Thank you!

My experience with Qatar airway was very unsatisfactory. They lost my child’s stroller and I was told they found it and will send it to the hotel which was a lie. I had to go back to the airport baggage claim and pick up myself after trying to contact them many times!. There was a lack professional and communication. I am very disappointed in Qatar airway and will not be recommending them to friends and family nor will I be flying with them in the future.

Aircraft was spacious compared to American Airlines, food was great, entertainment was much better with a wide variety of options, and the crew was very polite.

Did not like anything. Seats were crammed, leg space was minimal and food was terrible. This was the first time traveling overseas in American Airlines and was the worst experience ever. Have learned a lesson to never travel in American Airlines.

what would have been better would have been that my booking not been canceled by the system and had I been informed that the booking had been cancelled by the system I could have immediately rebooked and not found out that there was an issue when I was told by the system that I needed to book in. It would have also been good if either the booking agent or BA or anyone been in anyway useful. In the end I had to rebook a flight at an additional cost of $350. So no I'm not impressed by BA any of the other parties involved.

we had to walk up stairs to get into the plane--no jetways. Perhaps that's a problem not with the airline but with facilities at Heathrow, Glasgow, and Edinburgh. But it was inconvenient.

Boarding was poor. Why are first class passengers not boarded first?! Bus to the plane and then held on a packed bus because we were waiting for people on the bus before to finish boarding. Seat belt on the fist clas seat is very uncomfortable, cutting into your neck. Other than that crew, seating and food were all excellent. Entertainment, as usual - rubbish.

The flight was fine but no food available apart from snacks like Pringles and olives which was a problem for me as I hadn’t eaten anything that day. But the worst problem was BA left 24 suitcases in Heathrow as the flight was too full but didn’t tell anyone. So we waited for ages at Toulouse airport with no information and finally found out from the one member of staff in the baggage collection area who explained what had happened and apologised for no announcement being made but said that was their policy. Then BA contacted me today to say they have found my luggage and can deliver it to me on Tuesday - half way through my holiday!!!! So a friend has had to make a four hour round trip in his car to go and collect the luggage from the airport so we can get it today. A TOTAL SHAMBLES AND DISREGARD BY BA FOR THEIR PASSENGERS’ BEST INTERESTS.

Much much better than my previous times on British Airways the food was spot-on and the service was really genuine and attentive

Flight was delayed but my previous flight was as well so It worked to my advantage. This was my first time in first class. I don't think they ever stopped feeding us. The seating area was very spacious and comfortable. The attendants were wonderful, warm, friendly and very personable.

Flight was excellent, staff was great. My first time in first class and it was very relaxing and comfortable.

First time on BA but will fly with them from now on! Everything about the flight was superb!!!

Horrible experience. They broke the handle of my checked in suitcase and then refused pay for damages

We had a pretty good experience. Enjoyed both the flights. Crew was very good and helpful.
