Starting from this May 2018, international flights departing from / arriving to Aeroparque (AEP) will decrease of 50% and the remaining 50% should be cut off by April 2019.
It wouldn't be too much of a fuss if Ezeiza had better connection to the city. Last year I opted for a slightly more expensive flight because it was scheduled from/to AEP. I saved time and on the remise's fare.
