Not many Filipinos want to fly to Las Vegas, unless Pacman is boxing there, but a great many Chinese people from Hong Kong who have settled in Vancouver do like a flutter at the tables from time to time... this allows PAL to make use of its plane for a short hop and back rather than leave it parked pending the return leg, and it allows them to tap into a new revenue stream.
A sign that PAL now have real professional management.
