Hello All, I'm in the midst of planning a vacation for two to Chile and Argentina in March and I'm just short of 200k miles - so it looks like I'm flying C/F one direction and Y the other (perfectly fine with me). We plan on flying into EZE and returning from SCL. We'll be flying out of the NYC airports and there are so many options that I can't wrap my head around them. Now, availability will probably be the determining factor, but it looks like there's both UA (IAD-EZE), CM (JFK=EZE/SCL), and AC (YYZ-EZE/SCL) award inventory available for one or more of the flights in a mix of classes and I haven't even checked TA, JJ, or even CO out of IAH yet . What would help me a ton is to know how the level of service and hard product differs between the many options. I would guess that AC in Y is better than UA/CO in Y, but I have no clue about what international C/F are like on either and know even less about CM/TA/JJ. Is there an experience worth going out of my way for? e.g. is AC in F worth the positioning flight to YYZ? Is the Continental Club in PTY worth flying CM for? Any and all opinions are welcome Thanks in advance!
