Which constitutional provision grants Congress plenary power to regulate air travel as part of interstate commerce?

• A. The Commerce Clause
• B. The Necessary and Proper Clause
• C. The Equal Protection Clause
• D. The Supremacy Clause

Answer: (A)

The key idea is that Congress’ broad power to regulate interstate commerce comes from the Commerce Clause. Air travel that crosses state lines is part of interstate commerce, so Congress has plenary authority to regulate aviation nationwide, including safety and operations. The Necessary and Proper Clause helps Congress implement that power, but the authority itself rests with the Commerce Clause. The Equal Protection and Supremacy Clauses don’t grant this regulatory power.
