On a space-available basis, students may purchase the optional transportation package consisting of round-trip airfare (Ontario – San Jose, Costa Rica – Ontario) and round-trip transfers between the airport in San José and the housing for an additional $395 excluding mandatory U.S. government and airline-imposed departure taxes, fees and fuel surcharges estimated at $177 and subject to change for which students will be billed separately. A minimum of 10 students must purchase the flight for it to be offered. Participants have the option of purchasing their own transportation, but it is important that students arrive in time for orientation and the start of classes.
