I just departed through EZE a week ago and I would disagree with the other posters and encourage you to arrive at the airport 2 hours before departure time.

When we arrived at the terminal there was a huge line of people checking in to the coach area. I mean huge.

First you check in with one agent at a podium, then you go to the regular counter where they check you in as well as check your luggage (or not).

Then you leave that line and go to another line to pay your departure tax.

Then you go upstairs and go through the first area of security, where you show your passport and ticket again.

Then you get in line and get your passport stamped by Customs.

Then you go through a security area similar to the US where your bags go through XRay and you go through the metal detection doorway. My watch set off the alarm and I was wanded.

Then you get to the gate area. When you get there, there is a full bag search with every carry on bag opened and probed by customs.

Afterwards you are wanded by another security individual.

Then you get to board.

At each and every "stop" along the way the line queued up again.

Incidentally our flight left at 9:40, and we left the city at 6:30. By leaving at that time we had to deal with rush-hour traffic which took a full hour. (Also the cabbie charged us $AR70 which was fine, due to the length of time it took).

Also, we were passriders, and so our experience was just a bit (better) than reguar coach. First of all, we were permitted to go to the first-class ticket counter (the first stop on our way) where there was no line at all.

They gave us our boarding passes at 7:30 and were told to rush upstairs since they were getting ready to board our flight. We were two of about 8 passriders on that flight and one of the Delta agents followed us upstairs and had us move through the various lines to get us through as quickly as possible.

I don't know if there were other flights leaving at that same time, or if we were moved ahead of coach passengers (apologies if we did), but the point remains that we really didn't have a whole heck of alot of spare time with all the security measures we went through.

No, I would definitely give myself a full 2 hours at the airport itself to go through all the various steps in the process.

Good luck,
Rita
