1 8oo--942~o5~12 Porter's unaccompanied minor service is available only on nonstop Porter-operated flights within Canada and the United States. Connecting flights and flights operated by another airline are not eligible for the service. So before making a Porter Airlines child flight booking, look at the operating airline as well as the cities on the itinerary. A flight may appear straightforward during the search process but still be unsuitable if it involves a connection or another carrier.
