LS was actually the two letter code used from 1978 by Channel Express, the airline that became Jet 2 under the leadership of the present Jet2 chairman and many years before the move to Leeds was conceived. Jet2 inherited the Channex coding legacy.
The connection to a Leeds postcode was not intentional, but no doubt a handy marketing ploy for a business putting down new routes in the north..
Smart company!
