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

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

No entertainment but not expected. Unless you are referring to monitor that you can use. Then Al, was fine on all flights.

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

Not having to check carry on bags when plane wasn’t full. (The told us it was)

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.

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...

Very good service from San Jose to Madrid . Ryanair service from Madrid to Brussels 😕

Flight from Costa Rica to Madrid was excellent. Good food and service. The flight from Madrid to Brussels was very poor . No food , no entertainment, no usb … Total package was quite expensive so you should give same service on the second flight

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.

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.

The payment system was not working so was unable to connect wifi the entire flight

The boarding call announcements versus the Staff announcements versus the digital signage board on the out-going and returning flights WERE NOT IN SYNC. I was sent through check and re-checks 3 times. WHY?

Absolutely the worst airline. Can’t find anything positive to say. We were in business which is the same as most airlines coach

everything to do with KAYAK was terrible. Your customer facing departments are utterly useless, timewasting and unhelpful.

I ordered short ribs for main course. It tasted sweet, really sweet. Horrible.

When checking our bags we were told our bags would go through our final destination. This did not happen. When boarding, after group 3 it was a free for all, everyone boards. When served lunch, I asked for anything without dairy, I was given popcorn and gummy snacks. She said she would come back with more options, she never did. Also, when traveling through London, they don’t tell you your gate number until 1 hour before flight leaves, causing everyone to run to their gate.

Full flight, but crew was great. No wifi and no seatback entertainment, so had to read...argh!

The screen didn’t work and I didn’t get the seat upgrade I paid $300 for. They were no help with that,

The crew did not really interact with me which was no problem as I was fine. I did see that they were somewhat short with some passengers but that was not common. Just in general, they did not seem friendly - no requirement to be so but I am used to a friendly crew on most flights. The food was just ok but with a flight that large, I would think it hard to make something more elaborate.

Paid $180 for seat selection, and selection essnt honored. Have to call for a refund.
