Skipness - there are some routes for which either Gatwick is the main European hub point, or another major European hub does not have a flight at a similiar time, or the routing via another hub costs significantly more.
An example might be someone flying from Newquay via London to somewhere else - yes they can go take a train to Exeter and then go via somewhere else, but it's probably simpler to do a LGW-LHR transfer.
