my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

The flight was on time and the crew very professional. Everything went as expected and I will use BA again for this trip.

We paid to have overhead carry-on baggage. When we got to the gate we were told that our carry on bags would need to be checked and go below because the flight was full. Notably we were nowhere near the last people to board and about 30 other passengers also had to check their carry-on bags. Other than that the flight was fine.

Very bad plain although I paid A business class ticket I was stuck in a stiff fixed seat without any entertainment or Wi Fi for 5 hours I will never ever book a flight on British airline.

Self check in Kiosk did not recognize that I had prepaid for my luggage. This caused a 40 minute delay even though I had my British Airways email receipt for the prepaid luggage.

Crew were very friendly and helpful. They explained to us in detail the delay in our takeoff due to the storm that rolled in from Belfast and did their best to make up the time. Always great to fly BA!

Staff were very helpful. The free WiFi for messages was also very useful to keep in touch

Crew was more interested on looking at their phones than welcoming passengers during boarding.

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Missed my flight to final destination because of delayed British Airways flight. Had to spend 12 hours in airport and $1500 for new plane tickets
