Professional Flight Attendants Association
（重定向自PFAA）
The Professional Flight Attendants Association (PFAA) was an independent union which represented the approximately 10,000 flight attendants employed by Northwest Airlines in North America. PFAA had been the bargaining agent for Northwest flight attendants from June 2003, when its members voted to end their 26-year association with the International Brotherhood of Teamsters, until the membership voted to be represented by the Association of Flight Attendants in July 2006.
