No, Emirates is not a member of the Oneworld alliance, nor is it a member of Star Alliance or SkyTeam. Emirates has famously chosen to remain independent of the "Big Three" global alliances, preferring to build its own massive network and establish individual, strategic codeshare partnerships with specific airlines. For example, they have a very deep partnership with Qantas (a Oneworld member), which allows for reciprocal frequent flyer benefits and coordinated flight schedules, but this does not make Emirates a part of Oneworld. They also have partnerships with United Airlines, Air Canada, and JetBlue. This independence allows Emirates to maintain total control over its brand and service standards without being beholden to alliance-wide rules. For passengers, this means you generally cannot use Oneworld perks (like Sapphire or Emerald status) when flying Emirates, unless you are specifically using the Qantas partnership or another direct bilateral agreement.
