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.

So no I'm not impressed by BA any of the other parties involved.

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.

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.

The flight was very delayed in taking off - which was out of control of the crew, but then the pilot worked hard so we only arrived about 30 minutes late. Everyone was very friendly and accommodating!

They issued seat assignments and sat my 2 year-old in the row behind me, separate from me and my daughter. Communication/ customer service was terrible. They told me to change it in London, then in London, they told me to talk to the cabin crew, then a supervisor came and stuck us in the back of the plane when we were supposed to be in row 25. Overall, they need to really work on their customer service. Additionally the food was terrible and they ran out of meals and didn’t have any kid options. To top it off there was no in-flight entertainment for the first hour of the trip.
