A recent announcement by the Government of Baja California has sparked speculation that a brand-new direct, non-stop flight route reaching the major tourist hub of Tijuana could be coming to Vancouver International Airport (YVR).

Earlier this month, officials with the Mexican state proclaimed a “letter of intent” had been signed with WestJet for a non-stop, direct flight between YVR and Tijuana International Airport (TIJ).
