Excellent plane, smooth boarding Friendly crew Clean flight till end Food can be little better

The flight attendants went above and beyond to make a flight as comfortable as possible.

Our flight was delayed twice and after we boarded it was delayed again as they were searching for a passenger's small bag. We arrived in Hobart one hour later.

The seats are too close together and are smaller than they used to be. Makes for a cramped experience.

Great. Airhostess was amazing. Dinner a little spicy! Could have had a mention beforehand about that though

The international flight from Sydney to Dallas had great food. I have travelled a lot over the years and this has been the most memorable in my experience so far.

Initial flight was cancelled so moved to an alternative flight. As a result, stuck in a middle seat. Flight then place in holding pattern prior to landing resulting in a very late trip home.

There was nothing I didn’t like, prices a little lower would help

BA Airbus A380 BC upstairs had 2 3 2 layout. The seat was comfy but access for those in middle or window seats had to climb over others fest to get to ailse when seats in bed mode. The layout was not nearly as private as other layouts. The staff was amazing as well as the food. Most airline food is average but this was restaurant quality.

Following a marathon flight riddled by delays and changes from Santiago, Chile, my flight to Melbourne from Sydney was on schedule but I was transferred to the next flight. The reason by ticketing and the floor manager was I missed the entry to flight by one minute! That's right, the emphasised that if I was 1 minute earlier I would be on the flight. I asked what was the point them emphasising 1minute overdue and how that helped me or the situation. They didn't care at all. Replying that if it was one minute earlier they would've done something and smirking delivering the information. Australian's do call Australia home, Qantas calls Australian's suckers.

The delays and unpreparedness is horrible. Horrible management for missed flights. Aside from the the crew on the airplane was very delightful.

They canceled the flight and would not rebook us within several days

We have a lot to say when BA cancelled our flight the last minute and put us on Air France’s already overbooked flight; and took no responsibility to ensure we are safe and met our travels. It’s day 2 and we have not reached our final destination yet. BA took no responsibility, but were happy to keep the money! If it were not for third party ground staff at Dallas BA we would have not gotten to India. BA has a lot to answer!

Staff very good as was flight. Bad experience getting through passport control at Budapest airport. Very crowded, long wait and told to get in the wrong queue

5hour delay with a 3hour wait on board at the gate

we loved leaving on time, and appreciated that they were able to move our seats around at the gate

All fairly good as usual. Tried business class for the first time and enjoyed the inclusive champagne and good food. No entertainment as a less than 4 hour flight.

Flight crew were pleasant. I was switched out of the seat that I paid for and got placed to the back of the plane without being told. British airways should at least refund me the seat purchase for that flight.

Our seats were moved by ticketing agent at Chicago, so we thought we were getting an upgrade. Turns out we were put next to 4 children 2 of which cried or screamed for the entire 7.5 hour flight. It was a terrible experience for us.

The aircraft left 5 hours later than original dipartire time They let all passengers board and sit for 3 hours in a hot air plain with no A/C. Than they made all passengers leave the air plain due to some issues to the engine. Passengers received 1 glass of water the entire time . Than they boarded everyone again and took almost another hour before they took off. I bought these tickets for my 74 years old mother, Julianna Horvathne Kas and my nephew, Balázs Kelemen. Definitely going to request for a compensations!!
