We did not have enough time to make our connecting flight. As a result, we were put onto a different airline for our second leg. The different airline was NOT comparable to British Airlines, and our arrival was significantly delayed. The actual flight on BA was amazing.

We did not have enough time to make our connecting flight. As a result, we were put onto a different airline for our second leg. The different airline was NOT comparable to British Airlines, and our arrival was significantly delayed. The actual flight on BA was amazing.

Tv screens and movie selection v good. Friendly staff. They were really worried about max capacity and room for carryons. That is never fun but i had no problem finding space when I boarded.

British Airways is an excellent travel service. Comfort, food and airline personnel.

Good level of service. Comfortable airplane. However, security is always a hassle at LHR. I always try to avoid that airport at all cost if possible.

Everything smooth. The only thing is that my connecting flight in the US to my final destination was delayed. The time changed 4 times. For the rest, everything on time without issues

My flight to London from Philadelphia was cancelled due to weather.

Disliked having to wait a little longer to disembark from the plan when we landed in London

Food should be better quality. Video screens have poor resolution and the library of movies is poor. The other airlines are much better.

The trip was smooth but the crew were very abrupt, snatching things before finished and being quite snappy when asked questions.

My wife and I love to travel, so we fly a lot. We've already logged 381,075 miles and with practically every major airline. But this flight was very disappointing. It started off well, with no delays and a new plane. But when lunchtime approached, all that good impression was ruined. Instead of white tablecloths, we were offered small, dark placemats, which, as it turned out, were perfectly adequate for the food. All the food offered—and my wife and I only took fish, and the meat—was not just bad, it was downright disgusting and not heated enough. The same applies to the appetizers. This was the first time in many years of traveling that we've been offered such disgusting food.

Flight was fine - however my husband's checked in case was damaged, and mine still has not arrived

The pilot was professional and very good. The flight crew, very young and often looked flustered and overwhelmed. The seats were among the most uncomfortable in the air. The boarding somewhat chaotic. The price reasonable. Overall it was an average budget airline experience...although Iberia is not a budget airline. I fear if Iberia doesn't up it's game customers like us will go elsewhere.

The boarding procedure got confusing because they wanted to weigh everyone’s carry-on. Apparently mine was 3 1/2 kg over their limit. I didn’t know they had a limit. And at the check-in desk, nothing was said about this. They wanted me to check the carry-on at no charge and that would have been fine except then they told me at my connection in London I would have to go outside to baggage claim retrieve my bag, and then recheck it. In other words, they could not check it to my final destination, only to London. I told him this was unacceptable so after a few minutes of discussion, they came back and said that my bag would be OK to carry on the plane. It seems that if you have a connection then the weight is not as important. Then when I actually went to board the boarding agent said I needed a tag indicating that my bag had been weighed, even though she had just five minutes ago talked to the same person who cleared me. Lots of confusion seems like a very bad process. They need to improve this.

My flight being automatically moved messed up my travel plans, and I had to quickly find an alternative mode of transportation. I couldn’t get a refund from any of the companies involved. Kayak, Ibiza, or Vueling. I am still unsure of how to settle my concern.

I've taken British Airways before and it has been great. On this trip to Spain and Portugal we had two BA flights. On both flights we were taken by bus from the terminal out to the plane on the tarmac. There were many older folks on these flights, and to ask people in their 70s to lug their carry-on and personal items up the long mobile staircase to the plane entrance, is very disturbing. I won't be taking British Airways in the future. Many people on these flights were very unhappy.

why can't planes be boarded from back to front?? everything was great otherwise

The food on the flight was of marginal quality. Small bits of chicken, instant mashed potatoes and some carrots. The rolls were very dry, nearly inedible. The seats were quite small and didn’t allow for any shifting of position during the flight. There was limited leg room.0

The seats are so small that you can barely move at all. Don't try to eat with utensils in your seat either - you will elbow your neighbor in the face. Miserably small and I swear they are shrinking every time I fly. Food was meh (per usual), but at least there is free alcohol on an overseas flight. Doesn't make up for sitting in a torture chamber while hurtling through the air with hundreds of fussy people, but it's something. Entertainment options (movies, shows) are okay, nothing special, but at least there are screens, because most of the seats in these large planes do not have adjustable lighting - or air control - that you can get to, it's too high to reach - which makes reading impossible. Zero stars, AA.

Terrible customer service. I booked business class and the counter agent didn’t bother asking me about any choice or preferred seat, basically assigned me that last seat and couldn’t even answer if it was a business class seat. Also iberia lost my suitcase on my flight from JFK to MAD with the layover in BCN. Useless customer service at the counter. Thank goodness I happened to check the baggage claim area of the next flight in…there it was.

Good plane, excellent food, crew and entertainment. Seats in business could use an upgrade

Overall ok. Best part has always been the sundae dessert.

I’ve never been on a trans-Atlantic (or Pacific) flight where the seats don’t recline—not even a little. I asked my seat mate when BA starting doing this and he said “Oh, a few years ago.” I couldn’t sleep, with my head falling forward waking me continuously, and came off the plane incredibly stiff. I booked a Premium Economy seat to get a more comfortable seat, which was worse than most basic Economy seats I’ve ever booked.

Nice aircraft. Good crew. Delayed departure from Houston, but arrived on time in London. Main thing I don’t like about flying BA is having to transit through security in London Heathrow. A major pain!

Was upgraded to business class on this flight, I presume due to my premium economy class for my London to Denver flight. Business class was the same seats as economy, only the middle seat was unfilled. Decent lunch served, and the lounge experience in Prague was good. The only heads up I would give is give yourself enough time for gate carry-on luggage scanning, which I did not anticipate in my time planning.

Overall good, bigger chairs in the future would be nice.

I loved the food choices and the attentiveness of the crew but boarding was chaotic.

Great flight, last one out the air-conditioning was far to hot and the return it was to cold and then issued blankets. On the outward bowned the headset connector didn't work properly. You had intermittent sound from the audio socket.

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.

The staff was extremely friendly and nice. Overall, the flight was pleasant, and the food was good. They asked me to check in my smaller cabin luggage suitcase in Mumbai as the flight was full. Fortunately, I had packed a spare set of clothes in my laptop bag so I was okay.

Flight was delayed by over two hours and that meant my connecting flight was in jeopardy but there was no acknowledgement or help from the BA staff
