correct. Finish at the same airport you started at, whether that be by plane or by ground deadhead (IE, if a JFK trip ends at LGA for some reason, you will get a ground DH / limo LGA-JFK automatically built into the pairing). The ground DH may be deviated into an alternate deadhead flight home if desired, which can be nice when it works out.
