Great information on this post. I am thinking of booking CM for the very first time on points for business so have a few questions; planned route is EZE - PTY - YYZ
1) how's CM's business class? worth spending the points? I see it is not a POD style seat so already a negative
2) I can choose between 1.5 hr vs 8 hr layover. 1.5 hr seems enough based on comments here as I do not have to clear immigration nor pick up luggage. But what about track record of on time (it is out of EZE so not much faith there) factoring in the need to clear gate security even for YYZ
3) Is the COPA lounge still under construction and hence not worth the 8 hr layover? Can I visit the canal if I take that route?

Thanks in advance
