Mexicana's A319 aircraft seat 120 and are configured in two classes, with 108 seats in economy and 12 in business class.

Reader note:  leather seats, great pitch (seems better than QF long haul), comfortable for the three hr flight JFK-CUN, seemed a nice new aircraft. No IFE at all on the flight, no annoying boxes under the seats either though. Cabin crew were polite, spoke both English and Spanish, hot meal served (breakfast - omelette or french toast) and double drinks service FOC.
