I got an email about this (I think it was SF) for deals to LIM/BOG/SCL/EZE, BOG being the most expensive at around $460 USD I think, the others were all supposed to be like $250 on Momondo via "tripsta". I hate that Momondo site so many of the OTAs are sketchy.
That being said, when I started looking for a fare, they'd price at just over $600 CAD which is more like $450 USD.
I was definitely thinking of buying an EZE one since using miles to get there seems like a pretty tough ask sometimes and the fares are pretty nuts. Thought hey, why not use miles to like BKK or something with a "stop" in ICN. YVR-ICN-MEX-EZE-MEX-ICN-BKK-ICN-YVR.
Did anyone get it to price properly?
