The staff was fine in the fly, but to do check in was very poor the service.

Nothing that I like. Old plan.. old seats without maintenance. The recline seat in front of me (my was 10F) was 3 inches before my nose. It was not enough space to keep cell phone in hands. Even before landing the cruel does not pay attention to it. The worst flight of my life.

Booked my seat several weeks before and they changed it without consulting me to sit a whole family in the row sending me 15 rows to the back side, not caring if i have a short connection or any other urgent issue. The land crew made some silly excuse of a need to balance the plane because of the few passengers of the flight. Being a priority passenger it felt really a rude and careless attention from the airline

Friendly stuff , enough leg room in economy class, very efficient boarding and take off on time. There is no place to charge devices and movie collection is not to my taste. 9 hours of flight went very easy.

Very comfortable aircraft, plenty of room in the budget class. Especially liked 2 rows on each side with a 2-sitters. Staff is helpful and friendly. Food was actually very tasty. Negative- no self service electronic check-in counters which make the line much longer than could have been otherwise; outdated entertainment screens with limited choice of movies . Otherwise our experience was very pleasant and 9 hours passed without difficulty

They landed on the correct airport-no last minutes changes. Often times you hear of flight going to EZE but being diverted while on the air to AEP. It was crucial I landed in EZE as my international flight our of Argentina was taking off in 4 hours in EZE. Managed to do so and spare time to enjoy a coffee.

Old Plane with a broken seat. No food on the plane

Luggage is limited and the process for payment is convoluted. The crew is racist. Questioned why we were in upper class

My flight was cancelled over technical issues. They moved passengers to other flight that departed a few hours after mine. They left us for the 330 am flight (the original flight was 19:40). We went down the tiny Salta airport to grab dinner and suddenly they fixed the original flight and left, and never told us or made the announcement. It´s a really small airport, they could´ve looked for us, but didn´t. The flight took f with 8 passengers. And we got home after 6 am

There is no phone charging port on the plane. The infotainment system screen is small. The seats are very uncomfortable.
