Hundreds of United Airlines mechanics picketed at the San Francisco, Los Angeles (LAX), Newark, LaGuardia, Washington Dulles, Cleveland, Boston Logan and Orlando airports, to educate passengers about upcoming strikes, the company said.
A similar picket is planned at Houston´s IAH airport.
Mechanics recently voted down United´s contract proposal by 93 percent. Mechanics also voted overwhelmingly to authorize a strike. Over 9,000 mechanics at United are represented by the Teamsters Union, which is petitioning the National Mediation board for a strike release.
Founded in 1903, the International Brotherhood of Teamsters represents 1.4 million men and women throughout the United States, Canada and Puerto Rico.
