Boarding going from seated area to standing outside and then boarding the stairway seemed unnecessary. Drop the standing outside part.

Boarding going from seated area to standing outside and then boarding the stairway seemed unnecessary. Drop the standing outside part.

Check in at bcn was a nightmare. In-seat screen did not work, asked for help twice but was not able to use overhead light, watch the safety briefing, watch entertainment or monitor map

Really slow transfer after getting off the plane at Manchester, and lost luggage! Take the train, terrible experience on arrival

Over sold! Never again. Got bumped even though I checked in and arrived on time with all my documents in order. Wasn’t even offer food/drink voucher for the next flight that was 6 hours later.

The flight was canceled. It was very troubling because the rescheduled to Air France was two days later. I incurred two days extra of hotel, was not able to get a boarding pass until I reach the boarding desk at the airline. I don’t know what happened British Airways, but I was very disappointed.

There was a delay on departure. Seat configuration is horrible. BA should not fly this confirmation any longer until the new seat conjugation is installed. Your competition is beating you. Food was poor to average. Not many choices. Arrival was delayed at the gate due to another plane being at the gate. You would think after the delay at the departure, BA and ground control would figure out how to ensure you passengers wouldn’t be late and running to their next connection. Overall, BA continues to be very low on satisfaction. If I had an other choice, I would choose another airline.

Due to no fault of the crew or airline the flight left late but more than made up for it once we lifted off. Captain announced the delay was due to the plane was being worked on. Very friendly, helpful crew, who seemed to enjoy their job. Seats were very comfortable and appreciated headphones and the blanket/pillow in Business class. We were seated in the last row of Business class and they ran out of choices for the meal, however the Flight attendant was able to obtain a chicken dinner from another section.

We missed our connection because they loaded the plane wrong. And had to fix the weight and balance

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!

Flight was canceled with little notice or explanation. There were no other flights to Belfast from Heathrow, so I had to travel across town to London City (or wait until the next day).
