What is indicated by a "tarmac delay"?

A "tarmac delay" specifically refers to a situation where an aircraft is on the ground, either parked or taxiing, but unable to take off for an extended period. This delay can occur due to various reasons, such as air traffic congestion, weather conditions, or operational issues.

When passengers are on the plane waiting for takeoff without the ability to disembark, it characterizes a tarmac delay. Understanding this term is crucial for flight attendants, as they need to communicate effectively with passengers about the situation, assure them of their comfort, and manage any potential concerns that may arise during these delays. Thus, this definition aligns directly with the concept of tarmac delays, distinguishing it from other scenarios like delays in the air, at the gate, or those due to mechanical issues.
