Travel Transparency Act - Makes it an unfair or deceptive practice for an air carrier (including an indirect air carrier), foreign air carrier, a carrier agent, or a ticket agent to advertise or solicit air passenger transportation without disclosing the base airfare ticket costs and user taxes imposed for it. Requires the disclosure of any other government imposed taxes and fees paid on a per passenger basis to be clear and separate from the base airfare ticket cost in any such advertisement or solicitation.
