The arrival was pretty bad. Long waits for the bus to deplaning the airplane.

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.

Disappointed as we discovered when checking in at the airport 6hrs before the flight was scheduled, that we had been offloaded onto standby after having purchased these tickets months in advance. We had tried checking in online the night before but were unable to. BA had obviously over sold the seats, and we were told they couldn't confirm we could get on the flight until check in closed. Eventually we did get on but were not seated together. That was a bit of stress we just didn't need.

My flight from Athens to London was delayed 30 minutes. I got automatically booked on a different flight before the plane landed. However, I never received any notification about the new booking so I had zero knowledge about the flight number or even where to go. Checking in: it was absolutely impossible to check in for my flight online. I literally had to call British Airways to check in for my flight and select a seat. It was very inconvenient and a bit stressful.

I ordered a drink, but never got it. I ask what type of drinks they had and they could not tell me and there was not printed copy that I could find that is usually on most airplanes. They served dinner and never walk back to see if any need a drink or anything afterwards until they served the snack just before landing.

Check-in wait time was quite long (understaffed for the volume of customers), but energy and hospitality of flight crew was great!

I really enjoyed the flight…and food and the hospitality but didn’t get the food I requested for.

Everything was terrific. Kevin, and the whole crew, were exceptional. Five stars all around! Thanks so much.

Flight held at gate for other passengers. We ended up being late and missed connection

Should have more cosmopolitan food choices - too many Indian dishes - the only entree not Indian was lamb which I don't eat

The plane was ancient, and its technology was in disrepair. None of the charging stations worked, and the screens were barely functioning.

Worst thing: Luggage took forever to get at LAX despite priority bags. Best: Flight attendants were great!
