My route was Montevideo-Buenos Aires-Madrid-Rome
It´s a long flight, the worse part is the stop in Madrid around 5am local time to then take a conexion to a two and half hour flight to Rome.
I arrived exhausted, but overall it was not bad.
The service is good, and on time, legroom is standard (meaning tight) food and entertainment are ok.
The value x money is good most of the time.
I´d would fly again with this company. From where I´m it is one of best options available.
