The flight was delayed numerous times with inconsistent updates and very ambiguous information. When it was finally cancelled the logistics of handing out vouchers and rebooking was extremely chaotic. Meal vouchers were completely inadequate for the airport restaurants, and not even accepted at some. All-in-all, it was a very disappointing experience.

Terrible. The flight from Islamabad to London took 3 hours more then previously planned, I missed my connection to Chicago, and instead had to go New York, spend an extra day before arriving at my final destination. The return leg of the journey was similar. The connection time in Qatar was shrinked to less then an hour unannounced, I had to scramble to barely make it to my flight to Islamabad. Terrible experience, never using British airways again.

TIRED OLD plane. Seat cushion is completely old and NOT cushion at all; after an hour of flying butt hurts. Boarding is a complete disaster. No one respects the boarding groups, and the BA boarding crew care less about boarding groups or Tier status. What is the point of spending all this money on Business Class tickets when no one respects the boarding system? It took 90 minutes since we landed to get our luggage. 20 minutes to show on the screen which belt we are supposed to go to and another 1 hour to get our luggage - not the kind of service you will expect from BA at LHR

The crew on this flight were attentive, efficient and friendly. It really made for an enjoyable flight.

They canceled my flight , they put me on a different flight that was delayed and the connection was lost . They lost my luggage. And now I’m stuck with any of my belongings.

4 hour technical delay. Cancelled second meal. Crew and flight were great.

British Airways canceled our plane and gave us a new flight scheduled to leave in only three hours, so we had to drop everything and rush to the airport. The new itinerary only left us a one hour layover in Madrid, which was too short because the plane landed late and so we missed our connecting flight. We were then booked onto a flight scheduled to take off 8 hours later, and were not given any compensation or remedial measures.

It took over an hour to check in my bag a there was just one person at the counter. Security lines for business class also took a while. Although I reported 3 hours before my flight I made it to the gate 20 mins before boarding. To add to that jewelry was removed from my checked in baggage. I am submitting a separate complaint to Mumbai airport for that.

Everything was great except for online checkin. That was through BA- glitchy and needed help on seat choice in person at the airport (and the staff were fantastic). Unclear if the problem is due to booking lower fare thru kayak vs directly with Finnair or BA but seems to be the norm.

Seat layout, flight/club attendant service, food variety and quality could have been better. Business class Standard is visibly low compared with 6 other airlines that we have traveled for the past two years.
