Cons: "Customer Service is Dead with British Airways!!! I will make every effort not to fly with BA again"
Cons: "Crew could have reprimanded people not wearing their masks or not covering their noses. The airline could have kept middle seats open to instill more confidence in flying."
Cons: "Nothing!!! It was a great flight!!!"
Cons: "Size of the seats"
Cons: "Better drink selection"
Cons: "For an hour and one half flight the seats were tolerable. Anything longer than that would have been torture."
Cons: "Just wish there was another few inches width on seats"
Pros: "Friendly, helpful and professional crew."
Pros: "Excellence view of London performered by the pilot. Very please with that."
Cons: "All good except for the seat, let my neck with a bit of pain."
Pros: "The people from British airways were incredibly helpful."
Cons: "British airways pushed the flight time which made the original connection flight from Heathrow impossible. They notified justfly the company who we used to book the flight and told them the reservation would be cancelled. Only justfly never did something about that. They did not notify us about any changes and when we arrived at the airport the lady at the counter told us we don't have a reservation even though justfly happily took our money. If it weren't for the BA staff who rebooked is through Air France we probably wouldn't have made it."
Pros: "On time departure and arrival"
Pros: "Helpful and friendly staff"
Cons: "Filth plane"
Pros: "Crew very friendly"
Cons: "No free coffee."
Pros: "No hassle and all straight forward"
Pros: "Check in and crew were very nice"
Cons: "Baggage was slow But everything was fine Pilot kept us informed"
Pros: "Not much. Eventually got to where we were going."
Cons: "I can't remember a more cramped and uncomfortable flight. Missed connection on way Paris and we arrived 6 hours late. It took British airways 3 days to get our lost luggage to us. Delayed on way back, adding 4 hours to our trip because the first plane was not "serviceable" and they had to get a replacement. They arbitrarily decide who has to much carry on luggage and force you to check it last minute at the gate while letting others with same size bags take them on the plane. Certainly no better than bargain flights and possibly worse. Why pay extra? No more British Airways for us."
Pros: "I was very well looked after by crew."
Pros: "I like flights that land on purpose in a couple.troled way. This one did that. Good enough for me."
Cons: "Having to fly, but sometimes if happens."
Pros: "Short flight"
Cons: "All baggage lost. Wasn't put on the plane because they didn't have enough containers. Ground crew at London was courteous. Luggage had to be sent on to the US the next day. No free bags on this flight so all of the luggage lost had been paid for piece by piece. No free drink service; even a soda had to be paid for. No food, of course. Originating 10hr flight from Los Angeles to London was also uncomfortable, with small, packed coach seats, no air nozzles and poor headset connectors. I was very happy to get back on American Airlines for my return to Los Angeles. Wouldn't use BA again."
Pros: "On-time departure and arrival. Courteous efficient crew, both on land and in the air."
Cons: "My main gripe is that if you want a plain cup of coffee or a bottle of water, you are charged for it and can pay only with a credit card, but only if that card is chip and pin, and my US card isn't. Yes, it is high time that the US move into the current millennium and get chip and pin cards, but that is beside the point. I also flew BA from London to Seattle (part of same trip) and the on-board meal & drink service was PHENOMENAL - the best I have had on an airline in years, and I did not get charged for anything, including alcoholic beverages. How can this be the same airline?"
Pros: "Usual efficient BA"
Cons: "N/a"
Cons: "Had to take an emergency trip to London. The cost of the ticket for an hour flight was outrageous. $900 US was highway robbery."
Pros: "Certainly not the female airline attendant from Johannesburg to London on 1/4/2018."
Cons: "I boarded the plane and made a mistake by sitting in the wrong seat and placed my hang-up bag in the overhead compartment. When I realized that my actual seat was 10 rows back on the very last row, I moved, leaving my hang-up bag near the first seat. As time passed, I heard a woman on the intercom say something about a lost "jumper". After learning that a "jumper" is a sweater, I asked the nearby airline attendant if the sweater was a navy color, like the one that I had left in the overhead. A female airline attendant came to me, carrying my hang-up bag with my sweater and repeated 4 times that I was lucky because she was about to put my "jumper" and hangup-bag off the plane and leave it in Johannesburg since no one had responded sooner!!!! I was so stunned that I could not say anything. I only kept wondering why would anyone go into the overhead and start pulling things out? Why would someone take such extreme measures and not walk down the aisle, asking every person on the plane, including the people on the back row? This type of thing could happen to anyone. Since I did not have a name tag on the bag and I live in the US, it would have been near impossible to ever find my bag again if left in So.Africa! Plus, the woman went on and on in a very rude & condescending manor when all I could do was sit in shock, wondering why she would take the time to go through the overhead and look for a hang-up bag that does not have a name tag!!!!"
Pros: "I got there. It was safe."
Cons: "Entertainment system shut off."
Pros: "Crew, funny safety instructions with Gordon Ramsey"
Cons: "Delays"
Pros: "everyone was very nice-thank you"
Pros: "Bigger plane than I was expecting. Had I known that I would have upgraded to a better seat. I was just expecting a tiny puddle jumper so this was a nice surprise. Crew were nice, offered food/drinks but I didn't want to buy any."
Cons: "The plane had inseat screens but they said that licensing agreements prevented them from offering any video, games or news selections on a 2.5hr flight. The Pilot said he would turn on the in-flight navigator but it never did work, so I'm not sure what happened there. No internet connection in their fleet yet either. Clearly, this is a first world problem and I would still fly BA. But it's also 2017 and these features aren't "new"; I remember having in-flight entertainment back in the early 2000's on Delta flights in the US, so I'm not sure why it's taking more premium airlines so long to catch up."
Pros: "British Airways rescheduled our flights. The BA website was easy to find out how to claim additional costs incurred from the rescheduled flight."
Cons: "The flight was rescheduled within 18 hours of departure. We were in Spain on vacation which meant attempting to figure out how to get home with Iberia at the Madrid airport, who helped but was super agitated with us the entire time. When we asked for advice on how to proceed, as this has never happened to us before, they just kept telling us it was British Airways fault and that they had no answers for us. This took about two hours plus an additional hour back at the hotel to cancel our reservations in London and figure out how we were going to get reimbursed for the extra night at the hotel and additional costs. It would've been nice to get all of this information in an email, with the new ticket and instructions on how to claim the extra costs instead of us running around and taking time out of our vacation."
Pros: "On time"
Cons: "I have to pay for water?????"
Pros: "Comfortable and on time. We didn't have any food or entertainment so can't rate for them."
Cons: "After sitting on the tarmac (I understand the delay) for 2 hours there was no water available for another hour past takeoff. And then it was only available for purchase. Really, a cup of free water is asking too much?"
Cons: "Leg room/space BA offers is calculated for short and small body frame passengers and it is on not acceptable. It feels like cattle Wagon. BA should show consideration for real passengers not some sort of statistical average. I am 6'4" and sitting in your plane's cabin inflicts hours of body pain. The space given is sufficient for children and teenagers. Also sitting in the hot cabin for extended amount of time is extremely uncomfortable. Why there is no cooling and proper air ventilation right from the beginning?"
Pros: "Boarding seemed simple, no zones were called except for priority, we just all boarded and it seemed to go quickly and smoothly. BA is all pay onboard for any food or drinks."
Cons: "The check-in personnel refused to allow us to check bags until 90 minutes before the flight, then delayed that time three more times. This caused a real scene with nearly one hundred people standing around the check-in counter waiting to put their bags on the conveyor belts. The flight, which was delayed multiple times--once due to the ground personnel at Orly not turning in the paperwork for the flight--eventually took off, but the cabin crew seemed confused the whole time. We asked for Landing Cards, but they told us we did not need them, when in fact we did. That extra delay at immigration caused us to miss our connecting flight! Since half of the plane was connecting in Heathrow, why didn't the crew suggest that those staying in London wait on the plane until the connectors had a chance to disembark?"
Cons: "The cost to check in a bag was 65 pounds. We are a family of 3 and so that was 195 pounds. It is unreasonable to charge that much to check in a bag and ridiculous for ticket pricing to not be clear about this."
Pros: "Left on Time"
Cons: "Food costs money and not even water is free."
Pros: "Checking in online 24 hours prior to departure I received up-dates thrice regarding the delay of the flight which was very convenient. I had also learned about the protections that I enjoy as a passenger checking in online. The flight caught up in terms of timing as I had to catch a connecting flight to the continent from London. I was very pleased, also with the courteous flight attendents, the food, the entertainment selection and sufficient leg room in economy class. Overall a lovely experience, indeed!"
Pros: "I require a wheelchair for getting around the airport. When I first checked in at LHR, they claimed to have no record of my wheelchair request and my seat change, despite my very clear notations of who and when these were made. They did have a record of my paying for one suitcase. The agent at LHR promised to make these corrections so I would not have the same problem when returning to London. Furthermore, to turn this into a humiliating situation, at the gate I was informed that the jetway was broken and they would have to find some other way to get me onboard the plane. I cannot believe that British Airways has no contingency plan for a situation like mine. After many discussions between BA reps and ground crewmen they decided to bring me down in a lift at Gate 34, though my plane was at Gate 32. I was then loaded onto the freight platform of one of those food delivery trucks and driven over to my plane. The truck backed into place and again I hoisted up to the plane. However the plane door was locked and we had to bang on it for them to finally open it. To my great embarrassment I helped down the aisle to my assigned seat, looking back at the curious looks and glares from all those passengers who had no explanation for the delay and humiliating scene. Officially the flight was listed at 28 minutes late, when in reality it was 40 minutes till we taxied away from the gate My return flight from Brussels was little better because the changes that were supposed to have been entered at LHR never were and so I had to go through this whole routine again costing me over one hour in delays. Fortunately I was able to board the flight through the jetway and did not have to be hoisted up again, and delivered like freight. How would you rate these flights. I had problems with every single British Airways flight!!"
Pros: "We got to our destination safely which is always the most important thing."
Cons: "There didn't seem to be as much space as usual on international flights. The plane never got to a comfortable temperature and we were hot all the way home. One of our tv's didnt work which made for a very long 8 + hours."
Pros: "Nice plane, and quick flight to Heathrow from Glasgow. The plane had to leave late due to weather but the pilot kept passengers informed and made up time in the air so we were only 15 minutes late. The crew was available to discuss implications for connections."
Cons: "No entertainment options but this was a small plane and quick flight, so I didn't expect anything."
Pros: "Blanket and quiet to sleep"
Cons: "my screen didn't work"
Cons: "We arrived at the airport more than 2 hours in advance since this was an international flight. There was NO British Airways staff available to help with obtaining actual boarding passes which were NOT available on the BA mobile app. Although we made the flight with enough time, that was only because the security line was short and the passport control line was short as well. British Airways should have staff available to process passengers and boarding passes, luggage checkin, etc. earlier for their flights."
Cons: "There was a massive delay and I stood in line 6 hours to rebook. Because of the long rebooking line, I missed multiple other potential alternative flights that day and had to spend an unscheduled night in the suburbs of Glasgow. Had rebooking been more efficient, I could have returned home the day scheduled. Very disappointed."
Pros: "Crew was friendly, food was good, tv entertainment has a lot more choices now, decent leg room, smooth landing and take off,"
Cons: "Flight being late 2 hours and we had to sit in the plane for that amount of time, they didn't their refreshment service early"
Cons: "Everyone was terrible"
Pros: "All was fine ......cabin crew, pilot updates, seat comfort . Keeping hydrated is a well-known health fact. Why BA does not offer free water wa a shock to me . Yes a kind steward let me supplied with tap water, but I find it appalling that the corporate office does. It consider customers health important."
Cons: "Cabin luggage is too big for regional aircraft. Size limits need to be imposed more strictly."
Cons: "Boarding process was a bit chaotic. Announcement s needed to be clearer. Also all old movies on the IFE."
Pros: "Left/arrived on time"
