I travel often with LATAM, it never disappoints me. The service is great, nice crew, latest and some classic movies. I got 3 small meals, cannot complaint. I’ll definitely travel again with them.

I travel often with LATAM, it never disappoints me. The service is great, nice crew, latest and some classic movies. I got 3 small meals, cannot complaint. I’ll definitely travel again with them.

We departed and landed on time, the aircraft was clean and comfortable, the crew were lovely. Online checkin worked well and the self service bag drop at the airport worked well. The a/c was an Airbus A330 and has been fitted with a good entertainment system with lots of choice in many languages. The price I paid for the flight was competitive with other airlines apart from the budget carriers, none of whom I was familiar with so I stuck to an airline I have used in previous visits to South America.

We didn’t have any entertainment. I tried to go online without success. The airplane was extremely cold and they didn’t have blankets.

It was good, however the airplane was really cold. We received snacks and the crew was friendly.

Not sure why there are so many security checks at this airport. Consistently annoying showing passport over and over, checking carryons at gate all the while trying to make tight connection. Basically it was uncomfortable crowded cabin with meidiocre service

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

Although the flight is goof and the crew is good, the way the airline charges you for every service is ridiculous.

Plane never left the ground. Mech issues - entire trip was rerouted through united.

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

Awful. The flight wasn't actually operated by Iberia, but by American Airlines. I was unable to get my boarding pass and as a result missed my connecting flight.

The seats were way too crowded. Just because I do not have the luxury of a suite, does not mean that I want to fly from Austin to London scrunched between two people and the seat in front of me in my face. Ridiculous. I should have flown with Turkish Airlines...

Paid for “extra room” selected seat. Wasn’t a benefit. Also was in aisle and was bumped almost every time attendants walked down aisle. Should have saved the assigned seat money and let them select.

Flight from Madrid to Dakar had no onboard entertainment for a business class. Not even a single screen . That was disappointing. The WiFi only worked for the first 45 mins of the flight.

very good all round. staff, food, entertainment, punctuality all very good

The cabin crew were great very helpful and accommodating. We had a fellow passenger throw up next to us. The flight crew did an amazing job cleaning up and reseating us. We did question as to if he should have been let on the flight as his condition was likely self imposed.

A 13 hour flight with no food apart from what they offered from a menu you had to pay for. On top of that, there were no blankets, so during the flight when the cabin temperature dropped, everyone was very cold. Neither of these things were highlighted at the time of booking. This is the worst long-haul flight I’ve ever encountered.

online check-in was horrible and didn't work either way

The airline refused to board me because I showed up only 50 minutes prior to departure time, despite the fact that shortly before that, when I arrived at the airport still in time, they changed the terminal and I had to take a bus that took 20 minutes. Keep in mind that for some maintenance error I could not check in online like I usually do. Personnel at the airport was unable to let me in, customer care was beyond useless, the original airline operator (Iberia) was as useless as a toilet paper roll core in time of a wipe and all this uselessness made me waste my ticket, my reservations, my long time parking, food and most of all the joy of being with my family for the new year after working my bottom off even at Christmas. Am I happy? Come and ask me in person!

Boarding was delayed and we had to get on buses to plane so group # didn't matter. No food or drinks served gratis. Seats were small, knees smashed into the seat ahead, didn't recline. Crew was excellent though.

The flight from Seattle was delayed, which made me miss my connection to Florence. I was re-booked NINE HOURS LATER!!! That’s basically a vacation day lost. British Airways needs to partner with other airlines when possible to get a more realistic travel time, if delays occur. I realize there aren’t many flights to Florence from London, so I would book differently were I to return. The actual flight from Seattle was very comfortable and the crew was great, no faults there. I enjoy British Airways, this was an anomaly.

Our original booking with Kayak -our first experience -was exactly what we wanted and worked well. Updates were friendly and reassuring as were the contacts with UnderPricer so a big win-win. We learned a lot on your reliability and will definitely put you on our organisational list for the future.

The crew could not have been more helpful, my meal was excellent, I slept peacefully until right before landing, and the BA lounge was a godsend. The only negative I encountered was the coffee both on the plane and in the lounge. Not to my taste but that’s a personal preference.

Plane and seats ok. Dinners going and coming back were not fantastic. Breakfast from Seattle to London fine with bagel, cheese and fried egg. Second meal on London to Seattle not my favorite of kind of pizza sauce in a pastry. Came with water about three different times on each of my long flights. Staff on all very friendly and helpful.

I don’t understand why a reputable airline like BA would delegate their London flights to AA. Makes no sense to me, as most domestic carriers do such a poor job these days. Terminal 3 at LHR is a total dump

Uncomfortable seats. Crazy seat assignments separating families when they could easily have put them together. Good communication from pilot about arrival time after delay in departure. Toilet ran out of water in sink. Snack box poor for flight of this length.

The bed in Club class was not very comfortable, everything else was good.

Cancelled flight minutes before boarding. Rescheduled flight was two days later

The flight attendants were EXTREMELY personable and appreciated the service, lights going off after dinner (probably the norm, but I haven’t flown evening overnight flights in a while). Thank you!
