Saigon next year will be a SkyTeam hub, so hopefully next year. Vietnam Airlines operates a Business Lounge, for oneworld & it's partners (aka Korean Air) and maybe SkyTeam next year, Korean Air uses the Vietnam Airlines Golden Lotus Lounge as they code-share on every flight to & from vietnam & sth korea. Well not all Bussiness or First pax gets Lounge access, Star Alliance uses vouchers for spa, restraunt & other services.
