ARNet's wifi gateway is a disgrace. Make sure you have pen and paper ready to write down your login details because you're automatically logged-out after paying.
They don't provide any electrical outlets in the prescreened area but you can find a free powerstrip on the luggage security wrapping kiosk to the far left of the terminal.
I’ve never see this in my life. They made us wait at the airport for 11+ hours because it was raining. The airportstaffs didn’t have a clue of what was going on. I had to pay for my connecting flight
Be aware, do not get Pesos at the currency exchange stands in this airport, the rates are up to 30% lower than what you can get in the city. THEY ARE A TOURIST TRAP.
Incredible hostile inmigrations and security personnel if you have an Usa passport or Ue it seems to be worst. You have to declare even your own cellphone? Crazy!
Bad mood staffs. No free official wifi around the exit. Exchange rate here is very poor. Anyway, it's a very small and tranquil airport. The locals know it as Ezeiza, not Ministro Pistarini.
