Airline reviews

Pros: "It was short and with friendly staff."
Cons: "No complimentary refreshments."

Cons: "Best flight I have ever been on"

Pros: "Comfortable seats"
Cons: "Slow boarding"

Cons: "2 hour delay on an hour flight"

Pros: "When I finally settled into my seat on the British Airline and that Hostess came around and offered me a couple of free drinks that was the best thing that happened to me all day."
Cons: "For an older couple like us did not like having to climb the steps up into the Plane and being out in the rain did not help. However that was not the worst part of the arrangement between getting off the Aer Lingus plane and with so little time to reach the gate for our BA flight to Denver it was a total disaster. Due to a minor problem my wife had with her foot I had asked for a wheel-chair to be available when we got off the plane at Heatrow. Good job that I did because with out their help we would never have made it in time for your flight to Denver. Between up and down in elevators, running along the corridors, in and out of a bus and I myself trying to catch up with those poor attendants. I was sorry that I did not get a second wheel chair for my self. Only for the flight was delayed by about 20 minutes we would have missed the flight. Who ever was responsible for making the arrangements of just allowing a time of 1 hour and 10 minutes between flights needs to figure out a better time schedule before people of our age ends up getting stressed out and end up with a heart attack. Very stressful indeed, believe I will never let this happen to me again. Fly/Us you need to fix this."

Cons: "One person checking boarding cards at gate led to a ridiculously long queue for a nearly full flight and made it late getting us all on the plane and passengers were getting annoyed. Then whatever machinery Aer Lingus use to push the plane back from the gate actually got stuck on the plane cone leading to another delay. Knock on was we were made to wait for a take off slot and made to wait for a landing slot at Heathrow so late arriving."

Pros: "Reilly dolly"

Pros: "Efficient staff and timely I would book again for sure"

Cons: "The problem I had is that this was not a British Airways flight, nor were my flights to Dublin. I was not aware of this. When I checked in online I was allowed to check in with British Airways, so I had no idea that this was an Aer Lingus flight, which is in a different terminal with a different flight number. My phone didn't work in Ireland so it was extremely difficult figuring out where I should have been. If I was on a different airline that is affiliated with British Airways, and I booked through British Airways, there should be some way of looking up where I should be going. Also, any emails about my trip should have told me which airline I was on. I fly often, and often to other countries. This was the most confusing and difficult flying experience (the entire trip -- getting to and from Dublin) I have ever had."

Pros: "Friendly crew."
Cons: "Having to use steps at Cork airport . The cost of tea served in a disposable cup is too expensive."

Cons: "I'm soooo upset about the service after my flight canceled. 1.the staff ignored me when I asked if I could have a VIP to rebook my tickets earlier because my mom got cancel and was going to do the surge . But he went away and never came back, no any response of YES or NO. 2.I don't know why the airline company still need 11 hours to rebook the tickets with all our flight information and our passport liscen numbers already , making us waiting till 3 am at the airport. 3. I asked my boyfriend to talk to the staff on phone, and the staff told my BF that he didn't know my English was not good. I said to him loudly that I had told him , but the manager besides said "don't shout at my staff"to me, even without asking me what happened . I don't think that was a good attitude for the service department, especially to a foreigner. My email address is Chentongtong@wku.edu.cn"

Pros: "Preferential seating, though I had to pay for it."
Cons: "Having to pay for a cup of tea."

Pros: "Comfortable Clean"
Cons: "Food/drinks a little expensive"

Pros: "Very polite and helpful."
Cons: "Unknown"

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."

Pros: "The fact that there was no one sitting by me was fab. Through man on priority check in desk was very helpful getting me the assistance I needed"
Cons: "More choice of meal. Getting special.assistance.upon arrival at.Istanbul airport first outbound flight was hard. I nearly fainted as I had to stand for so long."

Cons: "Nothing!!! It was a great flight!!!"

Cons: "Size of the seats"

Pros: "Free service Food and coffee"
Cons: "Free service Food and coffee"

Pros: "It was incredibly quick!"

Cons: "Better drink selection"

Cons: "Nothing"

Pros: "everything"
Cons: "price and reliability"

Cons: "For an hour and one half flight the seats were tolerable. Anything longer than that would have been torture."

Pros: "I travel 70 times a year and I try to avoid BA the f I can. This flight 2 hrs late and they ran out of food as hey got to me I’m tge back. The toilets ran out of water 3/4 of the way through the flight so people couldn’t use the toilets. Not good. Zz"
Cons: "Gg"

Pros: "Helpful and Friendly Crew. Did their best to help during the delay. Able to take hand baggage on board (unlike our kid journey when forced to check it in at the gate)"
Cons: "Sat on plane for an hour waiting to depart, so delayed landing. The BA feel is no different to budget airlines now."

Cons: "Everything"

Pros: "The aircraft seemed new or renovated and it was fairly clean."
Cons: "The crew was talking with a passenger at the end of the corridor while laughing very loud. This caused many passengers to wake up from their sleep or just disturb them from their reading. Instead of telling the passenger to keep it down they were all cracking jokes to each other while the whole cabin could hear them."

Cons: "Just wish there was another few inches width on seats"

Pros: "Friendly, helpful and professional crew."

Pros: "Good service and crew."
Cons: "Seats were very very narrow."

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: "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: "."

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: "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: "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?"

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 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: "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: "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."
