The check in staff were so friendly and accomodating. Loved it. very rarefly you find that in other airlines.

They changed the flight and the airport on both legs of my flight which made it impossible to actually make the connection from one airport to the other in time. However the customer service agent at the international airport was very kind and helpful getting me on a flight for the next morning.

We were delightfully surprised with the exceptional ground staff as well as flight staff. Both did an excellent job of making our trip enjoyable and hassle free!

Please work on delays. This airline always has delays. The terminal is awful, aeroparque needs more transport for disabled people (terrible service), and proper equipment to deplane. It is the only place where I always have to use stairs

Delayed flights and cancelled flights …still waiting to see if the cancellations are refunded

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.

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

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

Not enough legroom on flight. I was never offered the option of purchasing a seat with more legroom.
