"The best thing was that the flight was not full. My 10y.o. was able to sleep over 3 seats. The timing was great too, the plane was leaving Chicago at 8:50 pm. That was a perfect schedule to settle down and go to sleep."

Pros: "Super friendly and never skipped the details."

Pros: "Service was good on the plane"
Cons: "Thought I had purchased an optima coach, but was forced to pay $60 baggage fee. At checkin, asked for aisle seat, but agent had already assigned a middle seat. Then asked to change to an aisle seat, but she demanded $30 to change. Aftwr boarding was complete, there were at least 6 aisle seats empt"

Cons: "I was very unhappy with Kiwi. I accessed Kiwi through Kayak where I had selected a seat with checked baggage. Neither the BA staff at Heathrow nor the BA staff at Chicago were aware that I had paid for checked baggage. After much debate the baggage fee was waived at both ends of journey."

Pros: "Crew was great and friendly. Seats were fairly comfortable."
Cons: "Our entire row's entertainment screens did not work and the attendants said (3 times) that they would reset our screens, but did not."

Pros: "Friendly crew,"
Cons: "Nothing"

Pros: "Punctuality!"

Cons: "Delay , rebooked on fight. Had to wait 8 hours. I needed a wheelchair .. they put Erin a remote location with a rude assistant in charge of transfers for wheel chairs . She had none. Made me walk 15 minutes to find a place to take my meds. She couldn’t care less."

Pros: "On time"
Cons: "Better more comfortable seats"

Pros: "Typical solid British Airways service."
Cons: "Delayd by 4 hours."

Cons: "We didn’t, have a wheel chare whan we arrived to Dublen we wait near 1 hair till they come"

Pros: "None"
Cons: "Flight attendance"

Pros: "When we finally took off."
Cons: "Flight was delayed >3.5 hours because of an "electrical problem affecting in-flight entertainment system and 1st and Business Class seats. After powering down the aircraft c. 3 times at 11:15pm CT the electrical system miraculously worked as normal."

Pros: "Very comfortable"
Cons: "Good food"

Pros: "At least we were able to wait in the lounge."
Cons: "One of the jet bridges malfunctioned. Had to board >500 passengers via remaining bridge. An hour late departing."

Pros: "Priority boarding and bulkhead seating for family travelling with infant."
Cons: "My 'infant on lap' (23 months old) was too big for the airline-provided seat (weight limit 12.5kg, and he weighed 13kg)."

Cons: "The airline sent me on a wild goose chase through the airport only to end up back at the same counter. They then told me it was too late to check in. Do not book tickets with cheapoair-British Airlines said this releasesthem from all responsibilities and cheapoair will do nothing but send you to different people trying to sell you another flight. It was the worst experience every!"

Pros: "Food was decent and it was nice to have all drinks included (but after the first one you had to go to the galley to get a drink)."
Cons: "Definitely an older plane with very narrow seats and very little legroom compared to other long haul flights that I have been on. They only delivered drinks once and then if you wanted any more you had to climb over people and go to the galley to obtaining yourself. Plane was also very warm so it was hard to get comfortable and there was not much airflow to cool you off."

Pros: "The crew was kind and patient."
Cons: "British Airways issued me and several others faulty boarding passes so I could not get through security and had to wait over 6 hours for the ticket counter to open so they could print me a whole boarding pass with a new barcode (I tried calling and they just told me to wait for the ticket counter to open). The emails they sent me with my tickets were all different and confusing, sending to different web pages to retrieve my boarding pass."

Pros: "The food, entertainment, and service was superb! Very easy to overlook how late the flight was. I appreciated the blanket and other items provided!"
Cons: "After a week, I still do not have my luggage. This is due to the flight being delayed 2 hours and I do not know why it was delayed. Because it was delayed, I missed my connecting flight."

Pros: "Good entertainment. More comfortable. The ride was smooth."
Cons: "Service. Having to ask for my food being skipped and also having food choices."

Cons: "Flight crew was just ok; nothing they did made me want to fly with British Airways again. Salad was good but the chicken nondescript."

Pros: "smooth flight"
Cons: "no dairy free food options"

Cons: "I had to cancel my trip due to a family emergency. The only way I could get a “partial” refund was to pay another $700. Makes no sense. I already paid over $1000 for tickets and you want me to give you another $700 in order to give me a refund."

Pros: "Everything was great! Good food and service. On time flight. No complaints!"

Cons: "no air vents over seats"

Pros: "Nothing"
Cons: "Fight was delayed 30 minutes so we missed our connecting flight to Madrid. We are stuck in London for the night, the food is not edible at the hotel they gave us and now we are stuck rearranging all of our future travel plans because we can't get to Madrid until tomorrow. This is our worst travel experience ever. We will never fly British Airways again."

Pros: "Nice aircraft and decent service. Cleanliness was good."
Cons: "The lie flat seats were good but cramped and claustrophobic near the head rest."

Pros: "Timeliness"
Cons: "Food and service could be better."

Cons: "Never made the flight"

Pros: "The check-in process at the airport in Chicago was efficient and the person who helped us was friendly"
Cons: "-I was unable to check-in online and I think it's because my name got messed up in the reservation system even though I entered it correctly -Compared to other airlines, BA does not stop by frequently to offer beverages. Food and beverage service provided by BA faded in comparison to what was provided by American Airlines on the way back. - Our flight was delayed due to weather, but we also sat in the plane for a long period of time with no explanation. -We appreciated that BA automatically re-booked us on another flight (although it was not the next flight), and provided 2 meal tickets for 10 euro each. There was no other compensation for the incurred delay (about 2.5 hours)"

Pros: "Entertainment system"
Cons: "The width of the seats in economy are so narrow they don't fit my back. I am not a fat person. 6 feet 170 lbs and fit. No legroom and the tray table is not deep enough to support the food tray. Breakfast after an 8 hour flight consisted of a Kellogg's snack bar in a wrapper. I am used to Southwest Airlines which allows more than one peanut bag so I took two breakfast bars and the stewardess scolded me and said only one and made me return my extra. Not everyone in my roll even took a bar. They treat you like dirt in coach."

Cons: "We missed this flight due to Kayak's failure to get us on any other flights to Chicago after our original one was cancelled."

Pros: "Flight attendants really are nice folks"
Cons: "1. Bought ticket via kayak chicago to prague, so I got outgoing trip on British airways but they codeshare it out to Aer Lingus. Unfortunately, these dumbos haven't figured out that no matter what the gyrations they do, I still want to be able to pick my seat beforehand. Nada. Not possible online. And forget calling aer lingus 800 number. called twice and was on hold for 30 min each time, they dont bother answering. 2. At airport, I was willing to pay extra for a good seat because of the issues above, so they said they would help me out. Ha - the manager who purportedly was helping me out gave me a seat up front next to a shrieking infant and behind a bassinet (he knew exactly what he was doing but didnt care). They really lie and think we're idiots. 3. Same thing for flight from dublin to prague. This time last row next to toliets Dont fly aer lingus if you dont book directly with them, same for british airways I looked at BA's website - they do let you book a seat in advance but you must pay something for every single seat. Crazy. There are no free seats"

Pros: "Got me there"
Cons: "Basic"

Pros: "New plane, very comfortable seating. The headphones in biz class were awesome, forgot I was on the plane. Overall best American Airlines flight and I do fly them a lot. Also liked the dual screens option."
Cons: "The seat control in the touch pad - not conveniently placed"

Cons: "The flight that I purchased from kayak had a 1 hour layover in London Heathrow. In order to make it to the next gate, I needed to go through security again and transfer terminals. There was no possible way I could have done this in an hour. You need a two hour layover minimum to complete this. As a result I missed my connection and was stuck in Heathrow for hours. Flights with this short of a layover should not be sold."

Pros: "Nice large plane that wasn't near capacity."
Cons: "Long delay with minimal compensation. Gave us a rebooked connection that we had near zero chance of making."

Cons: "It was extremely hot on the plane. for the first 30 minutes there was no ac available and there was little to no help from the staff. I asked for water to cool myself down and ov waited about ten minutes to get it after hitting my help button multiple times. The flight attendants may have been overwhelmed with the requests as there were many just like me who struggled so they came off very rude. The plane was also not updated at all - not personal entertainment and once again, no ac/air for people to control."

Pros: "Grest staff"

Pros: "Saved 5 hours by being changed to a non-stop for the same fee."
Cons: "Working with Iberia to get accessible seating took ten irritating phone calls."

Cons: "The flight was awful! Boarding was unorganized. Once on the plane, space was TIGHT! I have flown with Iberia before and had leg room and TVs behind the chairs. This was not like this. Seats were uncomfortable for an 8 hour flight, smelly, and flimsy. I have never been more uncomfortable. The crew were nice but one was very rude to a passenger snapping at him and all ignored a very drunk man on my flight as much as possible. This man was very disruptive for most of the flight singing, shaking seats, touching other passengers, and walking about the flight. I did not feel safe at all! The staff would tell him to sit down, walk away, and he would be instantly back up. Staff would see this and ignore. I had no idea what to do. I felt unsupported and unsafe. The flight had constant turbalence to go along with it. To the point that they canceled dinner. I wanted to kiss the ground when I got off the flight. This was absolutely miserable. I could not be more disappointed."

Pros: "A lot of people in close proximity. Very good service and food. It worked well."
Cons: "The flight was great but found out night before when I checked to confirm flights that ours were cancelled without notification. We booked through Kayak so not sure what happened. PANIC for sure but a great service provider spent an hour on the phone with me to make sure we made it."

Cons: "seats in World Traveller are the worst. I've never felt so painful sitting in an airplane seat. The curve of the seat makes it so that one must crane their neck the entire trip. The headrest sticks out a lot, further contributing to this problem. Anyone with half decent posture is going to have a bad time in these seats. I saw the club world seats while exiting the plane and wanted to cry,"

Pros: "I really liked how it was just one flight and no lay overs, the crew was very nice, and the food was good."
Cons: "It was very late and delayed."

Pros: "The crew was helpful and nice. The food was also nice. I had a gluten free meal and it was enjoyable."
Cons: "The plane itself was old there were no tvs on the seats so the "in flight entertainment" was awful. When you plugged headphones in there was an awful noise that prevented you from hearing anything from the movie/show. Considering this was a transatlantic flight, the plane should have been better. We were also delayed due to maintenance that needed to be done on the flight. Luckily London was my last stop so I was not late for anymore flights but a lot of people on the plane were. I was very disappointed and will be disappointed again if my return flight has the same issues."

Pros: "ORD -> MAD The flight was on time, it boarded on time, it took off only a few minutes late (you can blame that on incredibly crowded ORD). It landed, on time, to an empty terminal. The plane itself was new, very clean, and very well kept. The crew was friendly and spoke a wide variety of languages, including English, French, and of course Spanish. They had no issue with Latin American Spanish or European Spanish accents, which is a concern for some. Overall the flight got me to my destination on time, in one piece, and without breaking the bank."
Cons: "The seats, oh the dreaded seats. In economy class the seats are the most uncomfortable thing you can sit on for 8 hours. If they replaced them with plastic folding lawn chairs, you would have a better time. But that is what you get for flying coach."

Pros: "Flights on time. Food was OK"
Cons: "BA lounge cramped and unattractive. We were more comfortable in the general boarding area. Outraged that after spending over $7,000 on tickets, we had to pay an additional $241 to select seat locations."

Pros: "Crew was very welcoming"
Cons: "Overall long flight and connection from UK-Chicago-San Diego was dreadful without good food, entertainment"
