Middle seats SUCK!!!! I paid more money than I should have because of your terrible site Kayak.com. I'll try to use your competitors going forward. I am so disappointed you would play off business class.com as business class seats

Middle seats SUCK!!!! I paid more money than I should have because of your terrible site Kayak.com. I'll try to use your competitors going forward. I am so disappointed you would play off business class.com as business class seats

They lost my bag and I still haven’t received it yet

Safe and stable made me sleepy and I slept and dreamt 😂😂😂😂

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

Worst airlines either. First leg was delayed because of crew not available. My connection was missed so they booked me automatically the next day! But, impossible to get anyone on site, web site does not let me access my reservation anymore, confirmed by useless agents over the phone. My 2-leg trip with part in business class arriving at 4:10pm ends up in an awful 3-leg arriving at 9pm the next day with no way to even choose the seats and of course at the very end of the plane. I can understand problems arrive but the way Air France handle it is just unacceptable. You are on your own. Apparently getting you to your destination is the only thing they consider their duty. The customer experience and fatigue is none of their concern. And I have a status with them. I will reconsider my priorities when flying with Air France and encourage everyone to do the same.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

The food was great and the service and attitude was amazing!!

Old airplanes small seats expensive tickets, not as expected overall and not comfortable according to the price

Food could have been better especially the breakfast. Overall it was a good flight

Basic service for the basic price. Efficient and cost effective, so ticked all the right boxes.

Not constantly changing the price DURING a booking. Felt like bait and switch.

All very smooth airside. Check-in counters were understaffed. The wait is too long. Only two, then three counters were open. Waiting time of 35 minutes is too long. Pls review your rota.

To complex. So many types of fare. This made the boarding a caos.

Needs faster boarding procedure. Not their fault but should still take into account indifferent flyers.

J'ai perdu le billet 🎟 faute de visa j'ai pas eu de remboursement. J voulais prendre un autre Est-ce que yaura une solution

Bought check in baggage but couldn’t do it at the kiosk, had to line up just to get baggage tag which was a very long queue with only 1 customer service agent handling all vueling flights. Had to wait about 45mins just to get a bag tag and drop baggage.

You have couple of KG's grace on checked luggage

Le vol et l'embarquement se sont bien déroulé, mais une fois arrivé à destination nous n'avons pas trouvé notre valise. Nous avons été voir au guichet pour en savoir plus et c'est à ce moment qu'on nous dit que par manque de place dans la soute notre bagage est resté à Paris et sera enregistré sur le vol de demain et qu'il faudra revenir le chercher le lendemain à 16h. Le lendemain à 16h personne ne fût capable de nous renseigner et on nous à donné 3 versions différentes de la procédure à suivre. Finalement nous avons réussit à récupérer notre valise après 26h de retard. On nous à donné un numéro pour contacté la compagnie mais en appelant le numéro dédié à la France on tombe sur des personnes qui ne parlent qu'anglais ou espagnol ou bien on nous raccroche au nez.

The baggage policy is pathetic. We paid for our carry-on bags online. Said if we don't remove the wheels of our carry-ons it's not considered a carry-on. We all measured our bags according to the website beforehand. We were not refunded for our bags and were obligated to buy it as checked in bags for over $70 online or $90 over the counter. First and last time I travel with this airline.

Flight attendants need to come by a little more often to pick up trash.

My experience with British Airways was fine and dandy. Nothing truly negative to report. However, I was. asked to check my carryon bag all the way through to my desitination which prompted some huge problems. Thank goodness I kept a foldable-personal-item-bag in my carryon. I was asked to remove my valuable electronic belongings from my personal item bag, which was a camera bag full of expensive lenses and camera equipment, into another bag for the flight because it was "too big". Farbeit from me for asking further questions, but the bag was let through when I departed to Paris from America with no problems at all as I was able to explain that it was slightly oversized due to being a camera bag with a layer of protective foam which made it slightly larger. Still, this bag could and did fit perfectly under my airplain seat during my departure from America. On the flight back though, this was not the case and I was asked to remove highly valuable personal items, stow my camera bag in my checked bag, and then had to pay and overweight fee. Kinda bogus, but I was tired and wanted to get home so I complied. Regardless, it would have been nice to have had my bag retrieved during the London to Pittsburgh flight so I could put on new clothes and freshen up before take off.

Continue to be disappointed that the “food” for “ordinary” fare paying passengers is poor - on this flight it consisted of a packet of two biscuits and a small bottle of water … not even offered a “free” cup of tea or coffee. Suggest a review of the “menu” and offer a hot drink to ordinary (economy class) passengers. On this route there are many far cheaper flights available - paying almost £200 for a flight that could have been bought for less than half this price should have some “perks” - offering hot drinks to all passengers would, in my opinion, be a cost effective measure which would improve the image of British Airways.

Tickets get checked 4 separate times by different staff, would save time if only the person at the entrance and the person who scans the tickets checks them!

First of all, our gate, and perhaps all of British Airways' gates for Nice-Heathrow flights, led to a series of buses that took a long time to board, were crowded, and offered virtually no seating. The long line of passengers moved slowly. The food in business class was awful. There was an air traffic controller problem that caused our flight to be significantly delayed, and many of the passengers had connecting flights at Heathrow. While the crew acknowledged our concern and promised to give us specifics about where to go when we landed, in fact, no announcements were made, so passengers in that situation were anxious about how to quickly find their connecting flights. Not a great look for BA.

Fair, difficult to find the departure gate. Luggage delayed on arrival

Full flight, but crew was great. No wifi and no seatback entertainment, so had to read...argh!

The cabinet was clean and comfortable. However the seating selection process was not confusing. In the end three of us were seated separately.

We had to pay extra for seats and bags (even for an international flight). I paid for extra comfort seats, but it was under an overhead bin that the crew used for supplies. I paid extra hoping to get sleep. We were constantly woken up by the crew opening and closing the bins. Our seat shouldn't be considered extra comfort. We paid significantly more than the rest of the cabin for these seats

Seats small and uncomfortable (too firm). Boarding process is queue to queue. Food unexciting - and they run out of options very quickly.
