Airline reviews

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.

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.

Although the flight is goof and the crew is good, the way the airline charges you for every service is ridiculous.

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

They didi not provide wheelchair though we had requested. We had to run around for 40 minutes and arrange it from the airport!

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.

Basic experience, we were delayed causing less time to enjoy our destination and on the way back, we boarded when the flight should have been taking off.

reliable, relatively relaxed, helpful and kind staff and clean airplanes. No need for more.
