When evaluating the "direct threat" concept, what must airlines consider regarding passengers?

The concept of "direct threat" in the context of the Air Carrier Access Act involves evaluating whether a passenger poses a significant risk to the health or safety of others. Therefore, airlines must carefully consider the potential health impact on others when determining if a passenger's behavior or condition qualifies as a direct threat. This evaluation is crucial because it aligns with ensuring the safety and well-being of all passengers and crew members onboard.

Airlines are required to make an individualized assessment based on reasonable medical judgment and may take into account various factors, including the nature, duration, and severity of the risk posed by a passenger's condition. This ensures that decisions are made objectively and are supported by evidence rather than assumptions.

The other factors listed do not directly relate to the critical safety and health considerations central to the "direct threat" concept. Instead, they focus on broader implications or inconveniences rather than the immediate risk posed by a passenger to the health of others, which is paramount in ensuring a safe travel environment.
