EZE-DCA (or IAD) - EZE $608 all in in December - DL
Hey guys! If somebody is coming (or has plans) to the US I think this is a pretty good deal. Didn't try other dates or cities but I found it using Expedia and my parents are taking full advantage of it ^ ^
I try the same dates on Delta.com but couldn't come up with the same price.
Hope it helps someone!
