Decide where and when you'd like to go, but be sure to choose a destination outside of North America. There are no courier flights within North America.
Find a courier company by looking in the Yellow Pages under "Air Courier Services," "Air Transportation" or "Courier, Air Travel."
Be prepared to offer a $500 deposit that will be returned to you a couple of weeks after the completion of the trip.
Make your reservation through the courier company's travel agent. Call the airline a few days in advance of your flight to verify your reservation and request a seat assignment.
Pack sparingly. You can only take carry-on baggage since your check-in space will be used for the company parcel.
Upon arrival, carry out your agreed-upon responsibilities, such as delivering a manifest to a representative at the destination and completing paperwork.
