Yes Copa award space has shown up on Aeromexico's award tool for quite some time now, on AirFrance's as well, though the deals are typically not as good as booking Copa through either United Mileageplus (chase partner) or Avianca Lifemiles (amex, citi and capone partner). Copa's business class might be the worst of all latin american airlines, but they always have wide open availability even last minute, and its still a recliner seat usually with very convenient routing. Just try and time it so you get the 737-8 with the big recline, footrest and TV screen, not the older 737-8 version that has little recline, no footrest, and no screen. (Unfortunately since both planes share the same 737-8 the only way to tell is checking the flights one by one on expertflyer, one extra row in economy = bad plane). Sry, we are getting really sidetracked here think I need to start 2 new threads haha.

Also MaxVO Seeing Alaska show up as a Chase or Amex transfer partner would be everyone's wet dream. But Turkish, really ? Unless times have changed to book a ticket with Turkish you have to call multiple times and then when they find the award space you need to actually go in person to an office somewhere and if you don't have one close by, you are SOL. I'd rather just pay cash and not lose a full day thanks. I've heard sometimes they have some crazy sweet spots but when you have a massive amount of points would rather transfer fast then save 10 or even 20k points but deal with lots of phone hassle. Turkish is notorious for messing up award reservations (one time I got stuck in Africa because of them)

Also Citi and Capital One transfer to Turkish but i've never bothered. Seems too risky to transfer the points in and then you gotta go to some office and they tell you you can't actually book that flight, and you just wasted 50 or 80k points or whatever stuck in Turkish.
