Whereas passengers on scheduled international flights are usually asked to check in an hour prior to departure, charter passengers generally must arrive three to four hours early. Most of the additional time is spent standing with luggage in lengthy understaffed check-in lines. Meager in-flight amenities. Since economy is the predominating principal, don't expect much. Charter flights are notoriously late, often by hours and not infrequently by days.
Most charter airlines have a limited inventory of aircraft.
As a result, if one plane is delayed by mechanical difficulty, you have to wait until it's fixed. Unless the flight is delayed by more than forty-eight hours, federal law mandates no form of compensation. Charter airlines may adhere to less stringent safety procedures than do scheduled airlines. This situation was brought tragically to light in February 1996, when the crash of a chartered Boeing 757 off the coast of the Dominican Republic killed 176 German tourists and 13 crew members returning home to Frankfurt. There is a real possibility that the charter airline or tour operator will declare bankruptcy before or during your trip.
