Singapore Airlines and Virgin America have expanded their existing code-share agreement to include frequent-flier partnership. Through this deal, members of Singapore Airlines’ PPS Club and KrisFlyer loyalty programs will be able to earn KrisFlyer miles when traveling on all Virgin America flights, and can redeem their KrisFlyer miles for award travel on all Virgin America routes. Members of Virgin America’s Elevate frequent-flier program, meanwhile, can now earn Elevate points when flying with Singapore Airlines, as well as redeem their Elevate points for international reward flights on all routes flown by Singapore Airlines.
