A “nested” ticket is an itinerary within an itinerary.
A simple example is if I purchase a return airfare between Atlanta and London, arriving December 1 and departing on December 15, but I purchase a separate ticket for a round-trip flight between London and Sydney, arriving December 4 and departing on December 11.
The London – Sydney itinerary is “nested” within the Atlanta – London itinerary.
