THRU PASSENGER describes what?

• A. A passenger traveling in the cabin only
• B. A passenger requiring wheelchair assistance
• C. A passenger on a red-eye flight
• D. A passenger traveling beyond the first stopping point

Answer: (D)

A thru passenger is someone whose travel continues beyond the first stop on the same itinerary. In other words, their journey doesn't end at the initial layover—they proceed to a further destination after that first stopping point, usually on one ticket or itinerary. This distinction matters because it signals that the passenger will continue on another flight after the first leg, rather than ending their trip at the initial city. The other ideas don’t capture this travel pattern: simply being on a flight or in the cabin describes where they are, not how their itinerary progresses; needing wheelchair assistance is about accessibility, not trip continuity; and a red-eye flight describes the time of day, not the number of stops or how far the journey goes.
