What term covers all flights between and within the continental United States, plus parts of Alaska, Hawaii, Puerto Rico, the Virgin Islands, and Canada?

• A. Double Open-Jaw Trip
• B. Denied Boarding Compensation
• C. Connection
• D. Domestic Air Travel

Answer: (D)

Travel is categorized by geographic scope, and the term here describes flights that stay within one country and its possessions. Domestic air travel covers all flights within the United States, including its states and territories such as Alaska, Hawaii, Puerto Rico, and the Virgin Islands. Canada would be outside that boundary, making those routes international rather than domestic. The other options describe things that are not about geographic scope—double open-jaw trip is about itinerary structure, denied boarding compensation is about passenger rights, and a connection refers to a layover between flights. So the term that best fits the scope described is domestic air travel.
