I'm looking to book YOW (or YYZ if necessary) to EZE for December 2012 or January 2013 in economy for four travellers. Ideally, we'd also work in a stop in Santiago, but willing to forgo for simplicity's sake.

Can anyone advise when these flights pop up on the AC site? Right now, they're showing nothing, but I suspect this is because it's too far in advance. I want to get them in advance in order to use the least # of points possible.

I'm also willing to fly UA via Houston if necessary.

Appreciate your advice!
