Connecting flights booked separately, rather than as a single itinerary through an airline or travel agency, constitute a self-connected flight. For instance, a traveler might fly from New York to London on one airline, then book a separate ticket on another airline from London to Rome. This approach requires the passenger to claim baggage and recheck it for the onward flight.
Managing individual flight segments can offer potential cost savings and greater flexibility in route and schedule options. Historically, this practice became more common with the rise of budget airlines and online travel booking platforms. Decoupling flight segments allows travelers to mix and match airlines and potentially bypass traditional connecting flight pricing structures. This method, however, places more responsibility on the traveler for managing potential disruptions, such as flight delays or cancellations.
