Any good or bad experiences of Mexicana recognizing (or not) other OW elites following its membership of OW last month? In particular, are they allowing OW elites to use premium check-in desks and allowing us to board before the masses?

I'll be flying JFK-MEX-EZE with them next month and wondering what to expect from the Mexicana side of things. I'm assuming I will be able to access the AA Flagship lounge at JFK without problems.

Thanks
