I think pss refers to a pricing solution suite.

  It's "Passenger Service System" in this context. The core of where flights are sold. Killing off different GDS systems kills off individual sales channels. Killing off PSS kills the core of where it all lives, flights, seat inventory, pricing, etc.

  Passenger service system. It's the one that handles reservations and (usually) checkin.
