Your Final Destination is the last point on your ticketed itinerary. It is the destination shown on the booking you checked in with. If your trip includes connecting flights but was purchased as one single ticket, the Final Destination is the endpoint of the entire journey, not the intermediate stops.
For compensation purposes on international flights, the Final Destination is always used to calculate the total flight distance and the total arrival delay, even if a disruption happens on an earlier leg.
Example 1: You fly from Paris to London to New York on a single ticket.
If the Paris–London flight is cancelled, the Final Destination is still New York, and the distance is measured between Paris and New York (even if you never reached the U.S.).
Example 2: You fly from Knoxville to Atlanta to Paris to Milan on a single ticket.
Your Final Destination is Milan, and if there is a delay, it is assessed based on your arrival time in Milan. The compensation distance is measured from Knoxville to Milan.
Important! These rules only apply when all flights were purchased as one itinerary.
If you bought separate tickets, each ticket is treated as its own journey, and distance and delay are calculated per ticket, not for the whole trip.
