Took 3 people to the airport last weekend and it's the first time I've been there in over a year. Not a lot of changes but new paint and a new marquee moved down to the departures door.
The airport (Playa de Oro International - ZLO) is located about a half hour north of Manzanillo near the Jalisco border. Like most airports in Mexico the only transportation leaving is by taxi or rental car, no bus service.
