The Union of Southwest Airlines Flight Attendants


Representing more than 21,000 Southwest Airlines Flight Attendants, our Members are diverse, compassionate individuals who provide and care for Passengers across the Southwest Airlines system 24/7/365.


The Mission of TWU Local 556 is to provide, through collective bargaining, adequate wages, retirement, and safe working conditions for our Members. We promote legislation and engage in other activity to safeguard the economic security and social welfare of working people. To protect each Member from unjust discipline and to promote the well-being and continued employment of all Members.


Originally organized in 1975 under the umbrella of TWU Local 513, representing the Ramp and Maintenance workers at American Airlines, TWU Local 556 was officially chartered in 1981. Our first Contract was negotiated in 1975. Since then we’ve negotiated nine successor Contracts. Growing from 29 original Members today, TWU Local 556 represents more than 21,000 Members.
