[citation needed] There are three types: Using different airports in the same city is not considered an open-jaw, so a passenger on a London to JFK trip who returned from Newark would still be a simple round trip as both airports are considered to be serving metropolitan New York City.
A typical destination open-jaw would look like this on an itinerary, with the ARNK on the second segment to show that it is not being flown on that ticket.
In some cases, this type of arrangement is needed for boat cruises that do not return to the departure city.
In other cases, the traveller wishes to explore between two points and using alternative transport (e.g. buses, trains, ferries or flights on another ticket).
Another market commonly traveled under an open-jaw itinerary is the one of local one-way tours.
