Airline reviews

LATAM clearly does not have well-established policies re: luggage for international flights to Lima followed by domestic flights within Peru (in my case, from Lima to Cuzco). On the way in, they forced me to pay $50 in Lima to check my second carry on bag (the three bags were included in the fare from JFK to Lima). On the return trip, they told me at check in that I would have to pay $50 again at the gate (she said they couldn't accept the money at check in) Then, at the gate, they initially told me I would have to pay several hundred dollars to check the big bag through to JFK. I protested, and showed them a print out of an email saying the checked bag was included between LIM and JFK. Than a second woman showed up, and told me I wouldn't have to pay anything at all -- which was great news, of course -- but that means I was incorrectly charged the extra $50 on the incoming flight. Basically, just a mess. Also, their website is completely non-functional -- it was very cleear that all the airport staff knew the website was nonfunctional, too.

Good check in process Poor information on payments at Lima airport

Latam may be the worst airline in the world, far worse than even the lowest of low cost airlines in the USA. I wasted hours trying to PAY THEM TO CHECK A BAG! Then they misled me at the terminal, sent me through the wrong security line, the list goes on and on... Just absolutely terrible in every way. Avoid at all costs.

I was in the last row and they sent me to check in my luggage last minute after boarding. I had to go through the crowd.

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

Only complaint is that the entertainment system wasn’t working on our seats and some others.

Routine and on time flight with pleasant stewards and decent food. Nice experience!

You delayed my trip three days for no reason other than your lack of preparedness, did not offer any compensation, including food or a bed. I couldn’t trust you so I moved up my return flight and lost another day at the end of my trip to hopefully make sure I make my next flight. I will never fly LATAM again. You have the worse accountability and reliability and clearly do not care that your clients have lives and what it cost to fly to another country.

No air in the middle rows. Had a hard time breathing. Was dying of heat.

It was a good experience, the flight was a little too long & the food was ok
