Tour charter is scheduled around the itinerary, not the airport
Most passenger charter starts with an origin and destination. Tour group charter starts with an itinerary, arrival windows tied to connecting coach transport, hotel check-in times, and often a multi-stop pattern across a touring season. Aviall builds the flight schedule to fit that itinerary, rather than asking the tour operator to fit the itinerary around a fixed flight time.
This matters most for inbound tour series, where a coach and guide network is often booked well in advance around an assumed arrival time. A charter that lands even an hour outside that window can cascade into missed connections across the rest of the day's program.
