Jump Seating
A jump seat, or a dead head, flight is when a pilot rides on a flight as a passenger.
You may make a one-jump-seat flight from your Hub to another Airport to begin a new flight line. Once your flight line is complete, you may return to where you started to continue your original trip. (i.e., if your home hub was Seattle and you wanted to make a flight line in London, you could jump a seat from Seattle to London, make a complete flight line using London routes, then hop a chair back from London to Seattle. Jump seat flights differ from regular flights because they are not logged in your logbook, and you do not earn any hours or money for them.
