Local Lodges

Members of District 141 belong to a local lodge located within miles of where they work. Local Lodge Directory | Flyer

We represent more airline workers at more airlines and have more contracts for more full-time and part-time employees than any other union in the world.

More than just knowing our way around airlines and negotiating tables, we offer something other unions do not.


Only at the world’s largest airline union do you have a say in who negotiates for you, and who protects you on the job.

The world’s largest airline union is made up of a democratic system of local, district, and international lodges. Collectively, those lodges assure enforcement of your contract. After all, a contract with haphazard enforcement is barely more than a piece of paper.

At the IAM, democratically elected lodge officers, and a strong system of local lodges, assure you of swift and local contract enforcement by members of your own work classification.

The same is true in contract negotiations. At the IAM, officials that you elect from your own work group negotiate contracts.

Organizational Structure

Workers belong to one of more than 1,000 IAM Local Lodges that typically represent employees at one or more local companies. In the Transportation sector, District Lodges represent workers nationwide on specific airlines. There are three airline Districts and one railroad district in the United States and one airline district in Canada. The District Lodges negotiate and administer the agreements with the carriers under their jurisdiction.


The history of the Machinists Union is intertwined with the history of commercial transportation in the United States. Founded in 1888 by 19 railroad workers in Atlanta, the Machinists signed its first airline industry contract with Eastern Air Lines in 1939. Since then, the IAM has grown to be the largest and most diverse airline union in North America. Current and former Machinists Union members are employed at every major airline in the United States
