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.

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.

Need to pay for headsets, water, or any extra except air to breath.

Sitting space was very tight and I am not big or fat (I am 5'10" 178 Lb), so eating was very challenging. The rest was good.

Sitting space was very tight, so eating was difficult. But everything else was good.

12 hours flight. Only one meal, not enough food. At the galley only water during the flight. Lavatories not clean. Headsets at extra cost.

Need to pay for a cup of water. No food. Need to pay for headsets.

Everything should improve! Service like a low cost but prices like a premium airline. Crew in general with bad manners arguing for everything. You pay for priority access but then they use buses, so your loose your advantage to put your carry on first. That was the purpose for paying for priority. Bording is a nightmare, people accessing the plane for bothering doors, front and rear, no matter which line do you have.

It was fortunate that the flight arrived in London in accordance with schedule, and the luggage was promptly transferred to the luggage carousel. However, I find it concerning that even minor issues in economy cabins are prevalent within the industry. American Airlines, in particular, appears to have the least legroom and feels more crowded due to the proximity of neighboring passengers. Additionally, the crew’s adherence to protocol is inconsistent. While they may enforce certain rules set by the FAA on a select few individuals, they often overlook numerous violations, such as failing to reset seat recline during landing.

Easy and organized getting in and out of the flight

I liked the comfort of the plane. It was unexpected from past experiences.

Chair is very high. Your feet cannot touch the ground for 8 hours flight. It was a nightmare. Food was bad.

Flight was delayed 3 hours and 15 minutes. The delay caused me to miss my tour group due to arriving late.

Even in the premium economy, I found the seats incredibly uncomfortable. I hated that booking through Kayak, it wasn't clear that it was a Level flight, not Iberia. Everything felt cheaply made and not at all worth the airfare we paid.

Paid for my seat 4 months ago. Did not pay the extra for specific seat assignment ( never have and never was a problem). Could not electronically check in (found out it was due to overbooking and that unassigned seats get bumped first - never happened to me before). Luckily, did make the flight. Very stressful - would have been extremely disruptive for my travel plans. UK Visa - never notified by Kayak or BA that a visa was required. Had to spend 15 minutes to download and complete app at the flight counter and pay $25, and was told they would let me know in 3 days if I would get it (flight landing in 10 hours from when I completed app). Luckily, visa was approved before landing. Unnecessary stress created here. Food - main meal, curry chicken barely palatable with unrecognizable vegetable. Desert cup, cheesecake, also barely palatable. Salad cup was good. Small water offered only 3 times (before main meal, at main meal, at morning snack) - not nearly enough for long flight.

Luggage arrived damaged and protective plastic was lost. I need customer service to contact me or the number for customer service. Thanks.

Provided a good service and I will use it again. Thanks,

This ticket was canceled and I did not find out until it was time to check in. I believe the vendor is at fault. Cheap tickets.com I would like to elaborate on the situation to kayak. Can you give me an email address?

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.

The seat I was stuck in was so unimaginably uncomfortable. I have never had that tight of a seat in my 20 years of flying. Even budget airlines give you more space.

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

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

I have ordered Hindu or Indian vegetarian food, to my surprise they did not find any such request. All I ate during the flight was 2 pieces of bread. The airline hostess was completely rude and racist. She promised one apple and I asked he four hours of promise and she denied saying am not nice to her. Europeans seems to be having racism issues with Indians. I will officially launch complaint with Indian and USA governments They made to starve, I recently got open heart surgery and I am diabetic patient

Problems checking in. Charged for bag which was to be included. Repeated trials with in line check in process

Boarding was easy and well organized, Breakfast was not very good.

I missed my flight because previous flights came in late. Customer service hard to find and could not reschedule for the same day. Many people appeared to be behind the customer service counter, but only one or two willing to speak to the public. No offer to find alternatives My experience frustrating Very bad

My luggage is lost! I waited in Denver co and seen nothing almost lost my flight due to waiting for my bags and still nothing I hope to contact customer service today hope they find it

They gave us sandwiches as a meal twice. Snacks mid flight with cookies and a tuna panini. Then just the same tuna panini for dinner. That was it.

Top notch re cleanliness, comfort, operational. Attendants attentive, cheerful, courteous and professional. An unusually high-grade experience all around.

Everything. Boarding, service, food, seats, crew I'd increase the air pressure to avoid dry sinuses and after effects

The crew were great and constantly cleaning bathrooms and taking care of passengers. Flight was on time and arrived on time. Boarding was easy and hassle free. Food could have been better but decent selection. Overall recommend and will fly again.

At least it was a direct flight, however the boarding process was a nightmare. 2+ hours in line to check my bag. Then told it was overbooked and I have to go standby even though I bought my ticket months ago. Then sent to another line to get on standby - another long wait and finally started yelling that my flight was boarding. They sent me somewhere else. In the end I did make the flight - among the last group to board, even though I arrived 4 hours early at the airport. Worst check in process I've ever experienced in 50 years off flying.

Two of my four flights had issues with toilets either NOT fully operational or completely out of order. Boarding was a joke because they have NOT established who is running the show. In the end, she did a terrible job. The seats 💺 were loose goose and the drinks and snacks were limiting in choices. Also, following Alitalia as an inspiration was strange since they went out of business.

We had a 3 hour delay and then a long taxi to take off. It would have been helpful for the pilot to have communicated more about what was going on. There was no A/C during the wait, and the cabin must have been more than 85 to 90 degrees. The crew gave water to the people in the front but by the time they go to the back of the plane they stopped giving out water. Eventually I went back and asked for some in the rear of the plane (for a second time). The food was close to inedible. I thought on an Italian flight that the pasta would be better than the chick, but honestly, a Swanson's TV dinner would have been better. I had a bite or two to keep my blood sugar up, but basically I couldn't eat it.

Boarding was chaotic. Service was poor. Attendant was slow and rude. In business class, I was not offered a drink until 1.5 hrs,after takeoff. Food was inedible.

I don't like anything in this flight the food was bad the service was bad the flight was old and not connected to the screen no intertainments at all and it was long trip was bad intertainments the crew not helping

The company tries shamelessly to squeeze every dollar)Euro out of its passengers. During the check-in the force you to go through the seat selection, you can skip it. They will assign you the worst seat available, then show you the other available seats on the map, for a fee. But they won't show you the fee until you click on it. And once you do click, there's no way to unselect it!! You will get stuck and forced to pay for that seat. Cheaters!!

The flight was good. It arrived at Heathrow on time but then there was no transport to take us to the terminal. We sat on the plane for an hour waiting for a bus. I will avoid Heathrow if possible in future. The crew were very apologetic.

we had to walk up stairs to get into the plane--no jetways. Perhaps that's a problem not with the airline but with facilities at Heathrow, Glasgow, and Edinburgh. But it was inconvenient.

The seating has become ridiculous… like a contest to see how narrow and short they can be made- forcing anyone over 5’1 to pay more to not be twisting oneself into a pretzel. Really insane- would have thought BA was better than this. Frankly- it cancels out a lot of the positive aspects.

flight was delayed from BWI to London - missed my connecting flight & then connecting flight (also British Air) was delayed - food is awful, TV & movie selection is great

The flight was fine but they made me pay for my carryon bag because they said it was too big at the counter. But it fit under the seat just fine.

Super tight economy class. My knees were hitting the back of seat in front of me (I'm only 5'6"). My small backpack (sized according to their required dimensions) would not fit under the seat in front of me because there is a box (is that the life jacket?) in the way. Over all, extremely uncomfortable. I forgive the tasteless food, but the tight seating was torture

Excellent service by the flight crew, and the food was relatively very good compared to other airlines.

Flight was excellent, staff was great. My first time in first class and it was very relaxing and comfortable.

They can separate the young children from people who want to have a rest. It had lots of crying and loud noises from the children.

I had an awful experience with British Airways as they broke the handle of my checked in suitcase and when I went to complain they told me that this was not their responsibility. This has to be one horrible airline that does not take responsibility for the damage that they have created
