Our flight was cancelled and it took them 5 hours to reschedule and the next morning they said we still didn’t have a new ticket.

We departed and landed on time, the aircraft was clean and comfortable, the crew were lovely. Online checkin worked well and the self service bag drop at the airport worked well. The a/c was an Airbus A330 and has been fitted with a good entertainment system with lots of choice in many languages. The price I paid for the flight was competitive with other airlines apart from the budget carriers, none of whom I was familiar with so I stuck to an airline I have used in previous visits to South America.

We didn’t have any entertainment. I tried to go online without success. The airplane was extremely cold and they didn’t have blankets.

It was good, however the airplane was really cold. We received snacks and the crew was friendly.

Delta has an outstanding service. They are courteous and punctual most of the time. The flight departed a half hour late but we arrived 15 minutes early.

Not sure why there are so many security checks at this airport. Consistently annoying showing passport over and over, checking carryons at gate all the while trying to make tight connection. Basically it was uncomfortable crowded cabin with meidiocre service

Change of gate in Santiago devolved into half plus hour delay and a really tight connection in Lima

Plane never left the ground. Mech issues - entire trip was rerouted through united.

No entertainment but not expected. Unless you are referring to monitor that you can use. Then Al, was fine on all flights.

We boarded so late it caused us to miss time at Foz. No real information was provided to the passengers waiting.
