Outbound
Outbound generally relates to anything moving or traveling away from a certain place. When speaking of travel, outbound tourism means leaving one’s country of residence to visit a different country for a period of less than one consecutive year for leisure, business, or other purposes.
Outbound tour operators are travel companies that organize trips to international destinations (other tour operator categories include inbound, domestic, and ground).
An outbound flight is one departing from an airport to a point of destination, as opposed to inbound flights which arrive at the airport.
