Oneworld lounge access is available to oneworld alliance travelers with access to benefits within the oneworld Sapphire and Emerald statuses. Sapphire status allows you to access business class lounges and Emerald status allows you to access both first and business class lounges. To obtain oneworld Sapphire or Emerald status, you need to have equivalent status with the loyalty program of any oneworld airline member. For example, AAdvantage Platinum or AAdvantage Platinum Pro status with American Airlines would get you Sapphire status with oneworld. AAdvantage Executive Platinum status would get you Emerald status.
