Yep.... Y is 30K, J is 60K. Mexicana has only two classes of service, and due to recent cutbacks, its now quite mundane. The seats are not that great, footrests only on the 757, limited recline. For short hauls, amenity kits have been axed..... you get the picture. I have posted various threads on MX cutbacks in the front cabin. See also the Mexicana forum for more details (search out previous postings).
