Proponents of airline passenger rights reforms including U.S. Senator Barbara Boxer (D-CA) are expected to testify at a hearing today organized not by a committee, but by Flyersrights.org and the Business Travel Coalition. The groups are urging Congress to add guarantees that passengers will be treated like humans, not cattle, to an expected extension of the FAA Act that must pass by the end of this month (our most recent letter of support). Last night, Canadian musician Dave Carroll and his band Sons of Maxwell joined the advocacy groups and played their Internet hit "United Breaks Guitars," (video and sequel available at link) based on an apparent sordid episode of baggage-handler rage against the music. The event is open to the public from 9-12 today in Rayburn House Office Building Room 2200.
