If you are going to be in Argentina for the tour dates only, you should plan to fly on these dates:
Leave the U.S. on Friday, January 15 to arrive in Buenos Aires (BUE) on Saturday, January 16.
(Either Buenos Aires airport is good. Most flights go to EZE, but occasionally you'll see a flight to AEP, which is closer to the center of the city. For that reason, it's not a bad idea to search for BUE which covers both airports.)
Departure
If you are only attending the Buenos Aires tour, you would buy your ticket home for Monday, January 25, arriving to the U.S. on Tuesday, January 26.
