DPAX refers to which type of passenger behavior?

• A. Disruptive passengers who are under the influence of alcohol/drugs, disobey instructions, and are threatening or abusive
• B. Passengers who arrive late for boarding
• C. Passengers who want to upgrade seats
• D. Passengers refusing to wear a seat belt

Answer: (A)

DPAX focuses on disruptive passenger behavior that creates safety or security concerns on board. The best description captures the full range of such behavior: a passenger who is under the influence, disobeys crew instructions, and behaves in a threatening or abusive way. This combination directly threatens the safe and orderly operation of the flight and would trigger DPAX procedures. Other options describe issues that are not the kind of on‑board disruption that DPAX targets—being late for boarding is a scheduling issue, wanting to upgrade is a normal passenger desire, and refusing a seat belt is a safety rule violation but not the broader disruptive behavior DPAX is concerned with.
