Latam wouldn’t tell me how much checked luggage would until I was at the airport and they charged me the highest price possible. Besides that, it was okay.

Latam wouldn’t tell me how much checked luggage would until I was at the airport and they charged me the highest price possible. Besides that, it was okay.

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

Change of gate in Santiago devolved into half plus hour delay and a really tight connection in Lima

They didi not provide wheelchair though we had requested. We had to run around for 40 minutes and arrange it from the airport!

Everything was good except the check in. Could not do it online neither on the machines in the airport. Needed special assistance from the airline desk clerk

Great customer service, very accommodating. (Check in) Smooth flight, thank you Pilots. Only negative was one working bathroom in first class. Atlanta Base flight attendants were wonderful. Thank you for your smiling faces Delta..

The seats are getting smaller and smaller. Very uncomfortable trip. More than in other airlines

I do not speak Spanish or read in Spanish When asking for help, people were hard to find they spoke quickly and pointed a lot directions for where to go and what to do we’re unclear. Which made my traveling uneasy.

Flight was great Customer service was questionable until we found someone at checkin to help us. One young lady took all our passports disappeared for 15 minutes, came back with nothing done, handed to someone else and left for lunch. Very complacent. Baggage was very expensive until we went to the service counter and a separate person helped us. Even with platinum status they wouldn’t allow free bags. We will continue to fly Delta as our preferred carrier but will avoid checking in with Latam. Dr. Armand Radke

Horrible seat at the back. Crew was very kind. Packed plane. Wordy pilot bragging about Iberia being punctual when many of us came from Alicante flight that was delayed an hour and many lost connection and we lost our luggage. Still waiting for it

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.

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.

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.

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

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.

From boarding, to attention in flight, I couldn’t fault it.

The flight was delayed twice. When the crew explained about the debris causing flat tires, I was glad they took the time to change all four.

Overall great! They could add more entertainment option. They kept running out of vegetarian food options and I got travel packs. This happened on all legs of the flight. Need to plan for it better - I am sure you have some data analytics from all your travels.

Better service to offer drinks in the middle of the trip

They can improve Everything, a 12 hour flight has just 2 meals and the meals are 7 hours apart, wtf are they thinking. At the very least they should have 2 refreshments like some small snacks with some water or some other refreshments since there are people travelling with medical conditions. The services and seats were genuinely horrible

As I remember my last BA flight - mediocre at best. Uncomfortable with poor and minimal food and drinks. Screen broke shortly into flight so didn’t have access to entertainment either.

They gave away my business class seat. No explanation and no apology. Told me I had to take the downgrade if I wanted to get to India. Then no WiFi for 10 hours. Just ridiculous. We should not work with this company at Deloitte. They don’t know how to run a business.

The British airways from Dallas to London is not great , the food is not good at all but BA from London to Delhi is amazing food is great.

It made me feel safe that the crew diligently check our seatbelts. One crew member was so very patient with a passenger in explaining to him why his daughter’s car seat had to be buckled in a certain way. This passenger and his wife were quite argumentative and she maintained her composure brilliantly.

Missing 3 out of 10 checked in bags.Transfers in London and Chicago are chaotic.

Although we paid for pre-assigned seat assignments to sit together, on our flight from LHR to BOS our seats were reassigned at boarding with my 10 year old daughter seated apart from us in an exit row. We were assigned the last boarding group with little overhead space left when boarding. As a result my carryon was at my feet the entire flight making it very cramped.

Work being done at DIA made it difficult to find BA desk.
