Flight delayed due to ground hold. Republic airways did a great job.

The gentleman at the gate I think his name is RIE was exceptional

This was a Latam operated flight. Seats seemed a bit narrow in business class. Older aircraft.

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

I wouldn't say I liked being forced to check my small roller bag at the gate; too many people had bags and were in a higher boarding group.

715PM departure was 2.5 hours late. Received hotel & food voucher but after we already booked a room. Entire team just seemed like they were 2-3 steps behind in execution, and notifcations.

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.

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

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.
