Food is horrible. Flight was good and the staff were mostly men.

Delayed suitcase - terrible service to get my suitcase next day, I was informed it would arrive today in the afternoon (Jun/28). Now, I was informed I may or may not receive it until 3 am (Jun/29).

Seats not as comfortable as I had hoped. Food was very nice, service was fine. Entertainment options very nice. Had thought the premium economy was a more plus 2-3-2 layout but it was a 2-4-2 with seats not as wide as I had expected.

My bags never made it on the flight and I now have to wait for them to arrive hopefully tomorrow. You can’t even track your bags in the app to see where they are since they didn’t arrive. You have to file a claim and then wait for them to inform you when you will receive your bag. We were already delayed for an hour due to baggage so I don’t understand how my bag didn’t make the flight.

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

They are disorganized….show your flight info half an hour before take off, so you are running all over the place. Customer personnel are not helpful, and act like you are bothering them when you asked for assistance - very rude!!! My very first and last time flying with British airways… good thing we have other options.

My luggage did not make it. Will avoid Heathrow and British air

Overall flight experience was good. Unfortunately our process getting to our flight was a hit or miss. Our flight was delayed perhaps for the best as getting from terminal to terminal is very long and security had problems with the machines that delayed us getting to our flight. Heathrow security could care-less that you have a flight you are about to miss!

There was no entertainment offered or expected, so please disregard my readings of that component. The flight was fantastic. Efficient boarding, takeoff, and even early arrival!

2 hour delay with very little information given. Horrible service by BA employees at Heathrow after we missed our connecting flight. Extremely disappointing experience!
