A host of airlines now offer daily service to Manzanillo International Airport during the high season, which runs from mid-December through early May. In what is considered the low-season (although weather in Costa Careyes is optimum year-round), most carriers reduce service to Manzanillo to a few times per week. Airlines that offer service to Manzanillo include Alaska Airlines, Aero Mexico, Mexicana and Continental Airlines. While travel through Manzanillo is the most convenient access to the resort, regular flights are most abundant and frequent through Puerto Vallarta and the drive through the unique countryside is beautiful. Once in Mexico, transportation can be arranged from either airport with a 24 hour notice to the hotel.
