Most courier companies arrange for your payment at the time you make your reservations to serve as a courier on a particular flight. You receive your ticket on the day of the flight, either at the airport when you meet the courier agent, or at the courier company office located on or near the airport grounds. Couriers who fail to show up on time may be barred from taking future courier flights. If you wanted, you could probably be on a flight to some foreign country within 24 hours of receiving our information, especially if you're interested in Europe during the winter. Flights to the most popular destinations usually require at least a 2-week advance reservation, especially during the summer when advance booking can be 4 to 6 weeks or more to guarantee a seat.
Most people advance book in order to make sure they get the flights they want.
When courier companies are short of couriers for particular runs, the price usually starts dropping the closer it gets to the day or hour of takeoff. The length of stay in the foreign country varies according to the ticket. Nearly every flight allows you to stay at least 7 days. Fixed stays of one week or two weeks are common on the European trips. Flights to the Orient and South America generally allow longer stays as a rule, and sometimes require no minimum stay.
