I know that there could be a significant fare difference, but the cost of the one way is about the same as the round trip. I'm wondering if I should just go ahead and buy the round trip, wait to see if the fares go down, or maybe there's some fancy routing or something someone knows to get the ticket cheaper. I don't know what the normal price for a ticket to Argentina should be. I'm trying to fly out of MFE (McAllen, TX), but I could easily fly out of IAH or even SAT. Any airport in BUE is fine. We just need to get there, lol.
