The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

Great seat in premium economy, great food and drinks throughout lots of in flight entertainment. 1 hour 40 min delayed flying out , 2 1/2 hour wait at passport control in tampa

Have travelled business class with other airlines who profess to be the best in the world. They can however not beat the service and comfort that BA provide.

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

Checking in prior on line and wait time at Gatwick was terrible. I would rate a big fat ZERO.

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.

Boarding is always a challenge as folks in al groups crowd around for no reason, but crew handled it well. I once again applaud the LHR ground baggage staff as they got our bags from a flight at Terminal 5A to a flight in Terminal 5C within 40 minutes...amazing!

Why does a reputable airline like BA allow a miserable domestic airline like AA to operate its flights? There is no comparison between the two

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!
