Thousands of U.S. ride-hailing workers plan to park their cars and picket at major U.S. airports Wednesday in what organizers say is their largest strike yet in a drive for better pay and benefits.

Uber and Lyft drivers plan daylong strikes in Chicago; Philadelphia; Pittsburgh; Miami; Orlando and Tampa, Florida; Hartford, Connecticut; Newark, New Jersey; Austin, Texas; and Providence, Rhode Island. Drivers also plan to hold midday demonstrations at airports in those cities, according to Justice for App Workers, the group organizing the effort.
