I came through on Friday morning, and the delays were pretty long. Yes, its a new system, they take your digital picture and a thumb print, and no longer want the paper form (although the airlines still hand them out).

But the time at the immigration window was quick- seemingly quicker than before, when they used to type a bunch of info from the paper form. It seems the problem was a lack of employees- only 3 windows working the Argentine line, and 1 window each for the foreigners and reciprocity. Lines were backed up the escalator, and I was among the first few off the plane.

At least all the luggage was sitting there by the time I got out...
