We were not allowed to carry a bottle of water onto the 8 hour flight.

Good flight, boarding ok and crew very nice. Flight was not full so I was able to be very comfortable. Blanket and pillow provided with was good as it was very cold during the flight . Food was very good(small snack sandwich and an excellent piece of orange cake). Overall good flight, no complaints.

Check in -- in business took over 30 mins as there was only one attendant. Boarding was also a mess. The seat was too narrow and was not working properly. Food was very bad and the entertainment very poor. Crew was very polite and helpful, in fairness.

Poor handling of carry on luggage. We had a 8 hour stop in Santiago, are over 70 and, in spite of paying full fare they wanted to send carry on to luggage hold. No empathy. We had to show that several group 4/5 passengers were not sending their carry ons before they finally let Is keep them. Very poor .

Staff encountered friendly and helpful. Flight delayed 1 hour due to mechanical issue, but made it through Atlanta immkgration and security in plenty of time,

reliable, relatively relaxed, with helpful staff in all 8 flights we had on this trip. They are solid even though we did not have special seating or status for the flights.

The boading process was fine. Had to wait for bus from tarmac to terminal. Had to go through 2 or 3 security checkpoints in Lima to make next connecting flight.

The crew was amazing. The best in the last times. Great group of people.

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

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.
