Μειονεκτήματα: "The airplane was really old."
Πλεονεκτήματα: "Lounges are good"
Μειονεκτήματα: "We sure could do better refraining from serving food that has been opened, tasted, and rejected by another customer. Seat 34 A and B rejected their special ordered food for the wrong item. I watched them taste. Crew, one named Paul, took it back, simply put the foil back, and served to others."

Πλεονεκτήματα: "The crew were friendly, helpful and professional."
Μειονεκτήματα: "Those headrests need an upgrade in economy!"

Μειονεκτήματα: "Entertainment system is really ancient, it's lagging other airlines in terms of display size & quality, user interface and programming"
Μειονεκτήματα: "The aircraft (flight operated by American Airlines) was so old that in Economy class there weren't individual screens on the back of the front seat. I haven't seen anything like that since the 1990s! There was no USP or outlet to charge phones or ipads so i couldn't even use my entertainment. Passengers should be informed in advance or given a significant discount. Very disappointed."
Μειονεκτήματα: "The seats were too close. The food could have been better."
Πλεονεκτήματα: "Seats were comfy, good choice of films. Food was good."
Μειονεκτήματα: "There are other airlines with a brand I associate with more. Any airline can get me to London for more or less the same price; I may as well do it with a company that aligns with my view on life."
Μειονεκτήματα: "In our party of 3, one bag was lost -- apparently stolen at Rome airport. Nobody there from Aerolingus to go to! No complimentary food or even water from Dublin to Rome. Lousy food and expensive drinks elsewhere. Airplane from Dulles to Dublin ws old, unkept, antiquated. Serbve on airplanes was bad to nonexistent. NO coffee in the am after an overnight flight!!???"

Πλεονεκτήματα: "Boarded quickly and on time"
Μειονεκτήματα: "Baggage didn't make the connection. No free food or drinks"
Μειονεκτήματα: "I on line checked in but it only checked me in for this flight and not my next flight which meant I was on standby. Agent at check-in could not change it."
Πλεονεκτήματα: "The staff were all very friendly, and even though we did not get seats together at check in, the gate agent managed to find us seats together which made the trip more enjoyable."
Μειονεκτήματα: "I was disappointed to find that there were absolutely no entertainment or connectivity options on board a 2 1/2 hour flight. It's pretty much standard across carriers now to have at least internet access and a portable device entertainment option. I also did not enjoy paying for even the most basic beverages on the flight. Coffee, tea, and soft drinks should be included. You'll save a pound, but lose a customer."
Μειονεκτήματα: "British airways is a shitty airline, I was stuck in Heathrow for almost 2 days, pregnant and alone. British airways has poor communication, poor leadership and no customer service skills. My flight was terrible and I will never be flying on British airways in the future. I will also be telling friends and family about my experience and ensure that they also don't travel on this awful airline."
Πλεονεκτήματα: "The food was elevated and we were fed twice on our 9 hour flight! The beverage service was also provided often with a good assortment. I loved that there were new release movies available for free. The staff was friendly and available. If I were to do another long flight like that, I would seek out British Airways."
Πλεονεκτήματα: "The flight crew was formal without being stuffy. Gracious without being too familiar. (Although, I had an interesting -- and fun -- conversation with a great flight attendant, Suzanne on flight BA0115 on 5/21/17. Give that gal a raise!). Excellent service. Clean cabins. Lovely menu followed by delicious fare. Overall, great experience!"
Μειονεκτήματα: "The aircraft is illogically designed i.e. the awkward arrangement of seats in Business Class makes for an annoying obstacle for passengers who want to leave/return to their seats. But when they do settle in, it's as comfy as a cocoon."
Πλεονεκτήματα: "The attendants were professional and polite."
Μειονεκτήματα: "Food needs work."
Πλεονεκτήματα: "On-time with excellent entertainment system."
Μειονεκτήματα: "No wi-fi."
Μειονεκτήματα: "Flight was 3 hours delayed, the previous flight lost our baggage and we arrived in LAX at 11. We then missed our connecting flight from LAX to PHX. British a Airways told us that they couldn't do anything about it and we had to stay the night in the airport and get on the next flight at 6am from southwest."
Πλεονεκτήματα: "It was great. Staff was very nice."
Πλεονεκτήματα: "No complimentary food or drink London to Paris"
Πλεονεκτήματα: "Very efficient and speedy service delivering my delayed luggage on the way from Toronto to Amman."
Πλεονεκτήματα: "The gate agent"
Πλεονεκτήματα: "Nice staff, easy to board."
Μειονεκτήματα: "I was sitting in business class and the crew ignored the passengers for most of the flight. They sounded like they were having a party in the galley."
Μειονεκτήματα: "The low resolution screens and limited programming compared to other airlines and aircraft"
Πλεονεκτήματα: "Service was great."
Μειονεκτήματα: "Seats were very uncomfortable. No electrical outlets at the seats. No Wi-Fi onboard."
Πλεονεκτήματα: "No crying babies on the plane."
Μειονεκτήματα: "Uncomfortable seating. Business class was taken much better care of than economy was. Crew tried to be cheerful, but I was supposed to start the second leg at 6:30 pm (approximately), and i had to change flights, got on that plane at about 12:30 am and got into Heathrow late, missed my next connection to Prague, causing more problems when I got to Prague. Not even an "I'm sorry for the delay" from crew or ground staff. Everyone seemed overworked."
Μειονεκτήματα: "Some passengers were allowed to drink excessively becoming very loud and continually bumping into aisle-seated passengers."
Πλεονεκτήματα: "Super helpful Dallas staff"
Μειονεκτήματα: "The plane was parked not at the terminal, but far away. The one hour delay occurs because of 300 passenger transportation from and to the plane. This delay could be avoided if terminal services were more responsible. I always thought that the United provides the worst food in economy class. It appeared that BA food is even worse. The entertainment software was obsolete and delivered an image of a very bad quality."
Πλεονεκτήματα: "Speedy, timely, very professional crew"
Μειονεκτήματα: "A leg room is too small."
Πλεονεκτήματα: "The overall experience was very good from the angle of clean toilets, food and good leg space even in economy class."
Πλεονεκτήματα: "The plane had quite a bit of leg room, more than my flight from Denver to London. The movie selection was nice. Free wine and beer is always a plus. They gave a nice sized cup of coffee, but the coffee was terrible. The crew was nice."
Μειονεκτήματα: "The head phone jack only allowed sound in one ear. The food wasn't great, and the expectations were low."
Μειονεκτήματα: "The tickets were never purchased at British Airways. I showed up at the airport and nobody had a record of me ever purchasing tickets. By the time we realized that kayak had not transferred funds to the airline, the plane had left and I had to completely re-book my trip at triple the cost. I will be disputing charges and contacting fraud services to resolve this issue."
Μειονεκτήματα: "Video froze on volume screen and the food was bAd as usual on aa bread is particularly bad"
