Nearly 2,500 service workers – including cabin cleaners, wheel-chair attendants, baggage handlers and cargo workers – are currently negotiating their agreement with airline contractors at LAX.

The airline industry is projected to make $19.7 billion in profits in 2014.

The protest was scheduled to last from 11 a.m. to 1:30 p.m.

Workers and supporters started at the Tom Bradley International Terminal before marching to the LAX administrative offices located within the airport on One World Way.

Last week airport workers voted to authorize a strike if necessary to defend their right to unite for good jobs at LAX. A strike, if needed, may be called within the next week, union leaders said.
