We were not allowed to carry a bottle of water onto the 8 hour flight.

We were not allowed to carry a bottle of water onto the 8 hour flight.

Comfort in exit seat was excellent. FLight crew and flight were excellent. However exit seat tray table was broken so could not use it. Entertainment monitor did not work at all despite attempts to reset it.

We traveled with two young children, and it was not possible for our family to be seated together. No one offered help or assistance to organize seating so we could sit with our kids. In the end, we managed to find two seats in Economy so I could at least sit with one of them, even though I had originally paid for Comfort+. In summary, I had to downgrade my seat just to be able to sit with one of my children, which was very disappointing

I booked a flight through Kayak to Brazil I have traveled to Brazil several times before Kayak Delta or LATAM never mentioned during the booking or in the pre flight process that the visa requirements to visit Brazil have changed earlier this year. I was unaware of this change and as such never got a visa and was unable to fly from JFK to Sao Paulo Add to this that Delta allowed me to fly from Boston to JFK which they should not have as I didn’t have a visa. It has been a terrible experience and a huge loss of money

Good flight, boarding ok and crew very nice. Flight was not full so I was able to be very comfortable. Blanket and pillow provided with was good as it was very cold during the flight . Food was very good(small snack sandwich and an excellent piece of orange cake). Overall good flight, no complaints.

Wish the seats were a little more comfortable.. it was a 6 hrs nonstop trip. But the crew was courteous and w a smile

Poor, the airline was not able to help me move flights.

Check in -- in business took over 30 mins as there was only one attendant. Boarding was also a mess. The seat was too narrow and was not working properly. Food was very bad and the entertainment very poor. Crew was very polite and helpful, in fairness.

The plane broke down at the Lima stopover and they offered to put me on a flight the be t day but I had to be back in LA that morning and so I had to buy another ticket from Avianca and United for $2k I asked LATAM for compensation and received none. Very bad experience

Poor handling of carry on luggage. We had a 8 hour stop in Santiago, are over 70 and, in spite of paying full fare they wanted to send carry on to luggage hold. No empathy. We had to show that several group 4/5 passengers were not sending their carry ons before they finally let Is keep them. Very poor .

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.

the seats were so cramped you could barely move. it was difficult to eat when passengers would recline their seats. the seats were so flimsy and unstable that whenever someone got in and out of their seat, it bounced like a spring back in your face. the movies were nice. the food was terrible. even though the conditions were terrible, they tried to pressure passengers to relocate their seats to accommodate adults who were related and wanted to sit next to each other, even after the passengers expressed that they did not want to move for that purpose. on the connecting flight, the “service” consisted of items for purchase. even though the flight was only 45 minutes, once again passengers (including me) were pressured to relocate for people to sit next to each other. they couldn’t be apart for 45 minutes? this was much less compelling than being apart for an 8 hour flight.

Everything went smoothly, and we even arrived 40min earlier than scheduled, on an Orland-Madrid route.

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.

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

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

Flight to get to Barcelona was cancelled and then the next flight was overbooked. Cancelled the entire trip and went elsewhere. Fighting with iberia to get my money back. Ill never book this carrier again!

Transportation from gate to airplane was poor we stayed in hot bus for 20 minute no vantilation

No WiFi on the plane. Crew was insensitive to my medical supplies and medicine in my carry on. If the crew was monitoring passengers putting 2 bags in overhead bins there would be room. We sat for 2 hours extra. Iberojet is horrible never again.

There was no water in one of the sinks in the executive area, which is unacceptable as we could not wash our hands after using the restroom

Like I said the experience was mediocre. Nothing special about this airline.

This flight was delayed by more than an hour. The seats are uncomfortable ans do not recline properly. I prepurchased a wifi pass, but wifi was not working on this flight at all. The food was bland.

Food situation was bad. Also movie choices when compared to other airlines was terrible. Seats very narrow. My tv didn’t work.

I was not allowed to cancel the flight, customer service is atrocious

Great staff, just very far from the main terminal, had to run to connect my flight. I had 90 minutes to spare. But my flight from Chicago was delayed also.

My luggage is lost and nowhere to be found, no response from airline

Boarding was a shitshow. Had to bus to the gate. No separate bus and boarding process for Business Class.

The plane was very old, no power outlets. We also had to wait a long time to board. They kept moving us to different lines before we actually could step foot on the plane. We ended up being delayed an hour but we were never told or informed for any reason. After the meal I asked for a coffee which the flight attendant forgot and I had to ask again. Overall not the worst but not the best experience.

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

I liked the crews attentiveness, all food and drink items were tasty, and came out in a timely manner. The entertainment systems were not as responsive and my seat had issues with the auxiliary for the headphones. Seats were OK, and the headrest for my seat could go back only so far. Bathrooms were tight fit.

It was freezing. I asked crew member for a blanket and was told it might be in front of plane but I never got one. I turned off all the vents but still froze.

Food was great but they didn't clear my meal tray for 3 hours. You'd think they could check though the cabin now and then.

Check in could have been a little cheerful rather than dour

The media system is so inreliable, it keeps freezing and restarting at the begonning. Old planes with an old entertainment system makes a long flight very boring

Lufthansa charged me $280 to take skiiis when in the US the boot bag and skiis are one check-in bag. This was not advertised and a real shock at the airport. They only took the boot bag as a check-in item. The seats have been squeezed together like any economy airline and legroom is not as good as it used to be. Otherwise, the flight was fine and staff was helpful for making my connection.

You gave me a “Never fly Lufthansa” experience for life. You charged me $1760 for reinstating my ticket on a cancelled flight. Service at the airport was terrible. I’m convinced that I should never fly Lufthansa.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

Using the media screen in economy class is a disaster

This review if for American Airlines. From London to LA, British Airways customers flew American Airlines and there was a small incident on the plane with a customer that was sitting next to me. She had a gluten free meal which she selected online. The flight attendant brought her food and both times, it contained gluten (bread, cracker) and by the second time, the customer mentioned about the issue to the flight attendant because she is highly allergic to gluten. Customer was very gentle and just wanted to note that both her meals contained gluten on the tray. The whole situation could have ended really well if flight attendant just apologized and mentioned she would relay the message to the responsible party. Instead, she entered defensive mode and started making some BS excuse about how the cracker that was supposed to be mine, fell onto her tray instead. Mind me, I already had that cracker on my tray. I doubt I would be given two. Also, she mentioned that the bread from the previous meal was gluten free. REALLY? I ate that bread and it tasted like it had PLENTY of gluten. The whole situation was handled so poorly, not only by that one flight attendant, but by 2 others. The reason I intervened is because the customer sitting next to me was tearing and all she did was mention the mistake which could have cause her health great damage, and instead she received attacks and excuses. AA, you should train your employees how to better handle situations like this. A 'well, I don't see why this problem is a big deal since you (the customer with allergies) read the ingredients and avoided eating the cracker that "accidentally fell" from the tray of the customer sitting next to you,' should not have been coming out of a flight attendant's mouth.

Continue to be disappointed that the “food” for “ordinary” fare paying passengers is poor - on this flight it consisted of a packet of two biscuits and a small bottle of water … not even offered a “free” cup of tea or coffee. Suggest a review of the “menu” and offer a hot drink to ordinary (economy class) passengers. On this route there are many far cheaper flights available - paying almost £200 for a flight that could have been bought for less than half this price should have some “perks” - offering hot drinks to all passengers would, in my opinion, be a cost effective measure which would improve the image of British Airways.

Aircraft was comfortable even in economy, clean. Entertainment screens were excellent and. Hoice was very good. Good was just ok. Crew was not bad.

Entertainment system didn't work well. Also no new movies and limited choice of other programmes. . And only one USB A charger option. Most modern electronic items needs USB C. Planes should offer both

I was unable to board the flight because I was unable to acquire a visa , Brexit changed my ability to get an ETA, I’m a Trinidad citizen and it takes weeks to get a visa

The issue was not with BA it was with the link yoiu sent fopr booking the flight

The space in the seat was okay, the staff were friendly, the entertainment system, my touch screen was not working and some of the films listed on the website for the flight were not available.

BA flight from London NY had old BC configuration with 2+3+2 seating with open seats which was not comfortable and lacked privacy

Flew business- but plane was dirty, food horrendous. Too many business class seats diluted service levels overall.

Loved the boarding option from Business class lounge, experience on flight was excellent, plenty of good food choices
