Good for standing your ground on the taxi fares. It is usually best for the "uninitiated" to just buy the fare inside right before you enter the public area, with a fixed prepaid fare, and you can use plastic.
Every passenger is premium at EZE

, so there is no special line for people sitting in the cushy seats. The airport is a disgrace. If you go early to avoid the evening rush, hardly any lanes are open for security/migraciones. If you wait, then you deal with the mad rush of departures. I'm usually in the lounge within an hour of getting to the airport, but that is flying LAN J at a time before the mad rush of North America departures - but there's typically only one WTMD open when I get in the line, which can go back as far as the frosted glass barrier. More than once, they open a second while I'm in the line. They also started staffing more migraciones booths while I was in the line, and opened the second side. By the time I was through, both sides were completely full. I usually hear at least one airline sending a ground agent looking for missing pax in the migraciones line to try and expedite them. And that is the joy of departing EZE!
