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

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

Not very good, they nickel & dime you for better seats & pay extra for the checking in bag, bad service all the way around

Flight from Lima to São Paulo didn’t have USB plug to charge the cellphone.

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

Check in of my luggage which needed to be paid for was excellent. Thanks to Nora

As usual, LATAM tried to rip me off as a Gringo. They ignored the fact that having paid for my assigned seats, I was entitled to one free luggage per person, up to 10kg, and tried to charge me USD40 per item. While they ripped me off by $160 on my outbound flight (4 luggage pieces, which should have been free), I vehemently protested this time around. Note that they only request this from gringos, not from Spanish speakers. LATAM behaves like a racist extortion organization.

This airline is full of junk fees. After paying to get my kids to sit with me, we were asked at the gate to check in our roller bags and pay $40 for each one. Peruvian passengers all took their roller bag in the plane. I don’t appreciate airlines who spot the gringos to tax them more.

Pros: "Nothing as we could not take the flight."
Cons: "Allowing the option to change your ticket date, but failing all debit and credit cards payments offered, actually means that they are not allowing flight changes due to COVID related issues like they say they do. We had to book new tickets with another airline to get home."
Cons: "I needed to change my ticket and Kayak had another agency issue the ticket. Kayak does not change tickets and the third party and the airline said only Kayak could make the change. Having to purchase a whole new ticket from the airline, save the money and frustration and avoid Kayak and just book directly with the airline. The ticket would have and should have been changed with no fees. $325 lesson learned."
Pros: "Yes"
Cons: "Serve some type of beverage with out charging a lot"
