Nice to fly out of Orly smaller easier to navigate airport. Being able to receive boarding pass well in advance of trip was comforting to know all travel was in order.

Liked. The check-in was pretty quick as they had 5 desks working.

Generally a good experience except for boarding in Naples on the flight back to London. We were all standing around for at least 20 minutes maybe longer as there was no seating.

Seats, WC,sizes for today's generation adults, and if technical problems arise a complimentary coffee, water nice for waiting one hours, the rest is perfect (pilot and cabin crew)

Boarding was smooth and quick. Flight departed on time. Equally evacuation upon landing was from both the front door and the back doors. Bags were on the conveyor belts before I got there. Excellent service.

The terminals are far away, be prepared to walk. Also, You climb stairs to the plane since there are no aero bridges. Boarding was haphazard not in multiple groups, so stand in line early. Hard to find place to stow cabin baggage if you are behind in the line. You can purchase food on the plane. There are vegetarian options.

First -the flight was late - more than two hours Second, not even a bottle of water at bord to give for free for this inconvenience. Three-at landing ive realised that I've lost one of my ear plug headphones and been very desperate to find it with my torch, the crew not helped at all more than that they asked to leave the plane as everyone did before me. This was the last flight from that day- extra 5 min for me with a bit of help from crew - would have bring a super review. I guess this days humanity disappeared!

I got caught using a stolen credit card number. Michelle Siziba is my name Nice to London Gatwick on 7/31/25.

Not happy with price of luggage or that we had no choice but to pay whether cabin or hold. I didn't book seats but this is unnecessary extra money along with suitcase

We accidentally purchased twice the bags we needed. Our fault, but the ticket was not clear to us, and it asked us to purchase bags at checkin. When we notified them to get credit back at the airport, they said to contact customer service. We flew the flight and then contracted customer service. They said no credits after the flight has flown. Not customer service oriented at all. They know we didn’t check that many bags and kept our money for a service they did not provide. Be aware and very careful of what you are purchasing from them because they will not make it right if there is an error.

We always use BA due to the direct flight options, we have always had a pleasant flight with BA.

There might be more food options for people who can't eat so much starch/sugar/bread/rice. Meat, cheese, walnuts/pecans for snack, maybe jerky or other kinds of meat-based snacks would be better than bread and rice and sweets. I had an extra chardonnay, which was fine. The entertainment was great.

Unfortunately, my flight was cancelled because of some sort of emergency over the Atlantic and had to return to London. While I think British Airways made every effort to mitigate the situation, I must say it was still pretty unpleasant. I do appreciate the fact, however, that British Airways put my safety first…and I think the effort to correct a bad situation was very sincere. But I think the process might be handled better in future.

Horrible leg room - coach seating with empty seat in middle on a 3 across seating. You buy business class for comfort which includes leg room. Absolutely no entertainment options either. Awful experience

Crew service was poor and very little difference between premium economy and economy. Disappointed.

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.

One of the worst experience given the middle seat even asked for the change no one honored,boarded at the end and overall one of the worst experience

No WiFi in either flight. No leg room, the seat in front of me left dents on my knees and the tray was so low my knees propped it up if I tried to use it.

It was good although our flight to the UK was cancelled and rescheduled for two days later. This was after we were already seated on the plane. We missed the first leg of our trip. BA did put us up at a hotel and paid for our meals but we lost our hotel costs in Glasgow.

The crew was very nice and pleasant. We were very reluctant to book our flight with British Airlines because we had bad experience with their flight attendants on the previous trips, they were rude and not helpful.
