Know Before You Fly Act This bill makes it an unfair or deceptive practice for an air carrier, foreign air carrier, or ticket agent to fail to disclose in its Internet fare quotation a clear and prominent statement of checked baggage and carry-on baggage fees, along with a prominent website link to a list of all such fees. A covered air carrier shall publish on its website a clear statement indicating whether it will provide passengers whose travel is interrupted due to a widespread disruption: hotel accommodations; ground transportation; meal vouchers; transportation on another air carrier to the passenger's destination; and sleeping facilities, food, and water inside the airport terminal. A "covered air carrier" is defined as an air carrier that provides scheduled or public charter air transportation in an aircraft designed for a passenger capacity of 30 or more. The Federal Aviation Administration (FAA) shall designate a FAA office to receive and analyze reports involving fumes in the air conditioning and pressurization systems of commercial aircraft.
