Nothing I like, I missed this connection b/c of an earlier flight delay. I had to stay one more night and I paid out my own pocket. LATAM failed to send me to a safe and decent hotel.

Nothing I like, I missed this connection b/c of an earlier flight delay. I had to stay one more night and I paid out my own pocket. LATAM failed to send me to a safe and decent hotel.

It was delayed for 2 hours. Then when we arrived they took us on a very uncomfortable bus and left us there. The bus driver wouldn't let us out because no one from Latam was there. Everything was disaster.

LATAM is a great airline who takes care of there guests. They consistently walk around and see if you need water in addition to taking care of all the passengers. The chicken in process is really easy and I’m always offered a chance for an upgrade which I appreciate.

Deleted flight made me loose my connection flight now stuck in Atlanta for a day

Comfort in exit seat was excellent. FLight crew and flight were excellent. However exit seat tray table was broken so could not use it. Entertainment monitor did not work at all despite attempts to reset it.

I booked a flight through Kayak to Brazil I have traveled to Brazil several times before Kayak Delta or LATAM never mentioned during the booking or in the pre flight process that the visa requirements to visit Brazil have changed earlier this year. I was unaware of this change and as such never got a visa and was unable to fly from JFK to Sao Paulo Add to this that Delta allowed me to fly from Boston to JFK which they should not have as I didn’t have a visa. It has been a terrible experience and a huge loss of money

Wish the seats were a little more comfortable.. it was a 6 hrs nonstop trip. But the crew was courteous and w a smile

I like this airline a lot no problems at all, except being forced to check a carry-on bag ., Overall very good airline

The way the Pilot made all announcements, specially the way he congratulated the entire crew as the best team ever, making a comment that due to them they were able to shorter the delay to the destination. Amazing flight .

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

The flight changed gates multiple times and flight had to be delayed multiple times

We called Kayak for a change due to the TSA situation in Atlanta. What we got was a canceled return flight (in error) and we had to find the mistake. Not happy with Kayak who blamed it on AA.

I was in last row so that is never great bc the person in front of me leaned his seat all the way back into me.

Delayed for mechanical and no updates on what was happening and how long the delay might be.

My flight from LGA was cancelled and my rebooked flight from JFK was delayed numerous times. I will now be getting home after 2am.

Flight was delayed half hour before boarding, but when I checked flight aware the plane that would Pick us up had a delay of more than an hour. AA should let us know in advance to avoid waiting several hours in the airport

On the return flight, arriving in Denver we sat on the tarmac in Denver for over 20 minutes.

Typical AA - late by 90+ mn. Gate changed twice... Changed the departure time 6 times No explanation, no communication on reasons for delay I travel with AA twice a year... and it is consistently very poor.. I will continue to use AA only when i have to.

The flight attendant in business class was excellent! Professional, friendly and attentive.

Delays with no explanation. It could have been handled better.
