I had booked my wife and I on AR from BUE to MIA on January 10th and secured seats 6A and 6B. When I checked in AR claimed one ticket was booked for the 10th and one for the 11th. They forced me to by a new ticket and charged me an additional $2,400.00 USD. I want a refund. Rob Austin

I tried to add checked baggage through the website; the amount was charged, but the payment was not linked to my reservation. As a result, I had to pay again at the airport and only received a refund three weeks later, thanks to my bank’s intervention. The flight was delayed, and the boarding process was poorly organized. Several boarding groups were in the same line, which made boarding very uncomfortable. The food was acceptable, but the beverage service was limited. While drinks were available at the back of the plane, it would be better to offer more beverages during the meal service. On a positive note, the cabin crew was very kind and professional, and we arrived on time according to the revised schedule.

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

Boarding was uncomfortable. Groups weren't boarding in an orderly fashion because everyone was taking to buses together. It was 90 degrees, but there was no air-conditioning. We left 40 minutes late without explanation. Uncomfortable!

Outstanding service both from ground staff and onboard staff! Very helpful in making changes to our schedule when our trip ended sooner then expected

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

I flew in a new plane with an excellent crew.Felt great

My experience was TERRIBLE. They made me check my carry on bag, and they broke it. and then when I made the claim they said it was a small damage and that I would not be compensated.
