Boarding was chaotic(zones were a bit arbitrary) and we had to undergo a second check of our carry on bags and jackets at the gate...nobody was detained and nothing was removed just a waste of time as we already went through screening to get to the international gates .

Boarding was chaotic(zones were a bit arbitrary) and we had to undergo a second check of our carry on bags and jackets at the gate...nobody was detained and nothing was removed just a waste of time as we already went through screening to get to the international gates .

it was good. the seats are super uncomfortable. No room for legs at all. but the flight was good.

The AA lounge at EZE was poor. Poor food options and poor comfort. Looked dated. The plane was old, chairs not comfortable. My entertainment sec teen was broken. Poor movie selection. I normaill fly Delta and use the Latam lounge.

Fine; flight schedule was changed the day before but they sent email and called me. They took care of the rearranged connecting flight well.

my tv was a bit broken, and so was table, so the food would keep falling, as the table was loose. they weight the carry on, and make me take out 3 magazines from the carryon, given it was minimally over the 10pound limit (which was a bit ridiculous)

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

I had an 9 hr layover continuing on to Ushuaia. I expected to have to get my luggage & do customs but I did not expect Aerolinas Argentinas to make me sit with all of my luggage for 7 hours in the entrance part of the airport before they would let us re-check our bags & get back in where there are seats. People were sitting on the floor everywhere.

This is the worst airline I have used in my 30 years of travel. The boarding process was an absolute nightmare with endless lines. It took 4 hrs to get to gate while in Bunoes Aires. Also, they change flight times and gates several times leading us to go to multiple gates. Never will fly this airline again

Aerilineas changed my airport from aero parque to Ezeiza and didn’t take care of my transport. Seats were mediocre and ground personal weren’t very helpful. Too bad that’s the only option to fly to El calafate. Bad service, bad company

Better snacks options for a 3.25 hour flight . There was only 1 choice - a fruit granola bar .
