I do not read or speak in Spanish. Only English. When asking for help, the people spoke quickly in English and pointed a lot. I wish they would’ve spoken a little slower for me to understand. There was much confusion and hurried in their message and I was unclear as to where to go

Everything was as you would expect in coach - fine. Flight was close to on time.

It’s been some time since I saw the plane and the cabin that old and worn out.

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

I loved how polite the crew was even though some of them wasn't the best with English that they still done everything they could to help me with my needs food was amazing

Terrible They charged me 157$ for excess baggage even though my bags were within the normally accepted limits Flight was late. Service was poor. The snacks were really bad

Horrific checkin procedure with neither Delta nor Latam figuring out how to check me in. 4 hrs on customer support with both and both airlines pointing to each other who should do checking. I was not checked in until morning of flight, which for international flight is concerning.

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

We had 2 delayed LATAM flights in our trip. We were only given one coffee for 5 hours delay. Also when we were boarding the crew wanted to charge us for our allowed carry on luggage. I got a bit angry and they finally didn’t charge anything. Not flying with LATAM again.

the flight from Boston to Curitiba was on time actually 30 minutes earlier. latam was not able to unload the luggage for custom checkup in Sao Paulo ii took two and half hours . i missed the flight to Curitiba spend the night in hotel and then flying in the morning to Curitiba
