Copa J - Toronto Lounge Access?
 

I am using a United award ticket to fly PHL-YYZ-PTY-LIM. I have no *A status, all flights are J, PHL-YYZ is on AC, YYZ-PTY-LIM is on Copa. Does the J ticket grant access to any lounges in YYZ?

Your J ticket should give you access to any of AC's Maple Leaf lounges. Believe YYZ has three of them: domestic, international, and transborder.

Plus - as long as you travel on AC metal in C /there are some small aircraft with Y-class only/ - you should also get UA Club access in PHL.

PS. In YYZ you can only access International lounge - it is because of how the airport is set up.

PS. US-to-Int transfer in Canada requires you to clear Canadian immigration - make sure you do not need a visa for Canada (I believe you need one if you are a citizen of Panama, if you are a US citizen you will be fine) - otherwise they will not let you in.
