When you board a plane, a flight attendant’s greeting serves more than just politeness—it’s a safety measure. This brief interaction allows them to assess passengers, particularly to spot signs of intoxication. Since many travelers have a drink before boarding, flight attendants need to ensure no one is too impaired to fly safely.

Flight attendants are trained to identify passengers who may be too drunk or ill, preventing potential disruptions during the flight. The greeting also helps them identify passengers who could assist in an emergency. While it may seem friendly, it’s not about attraction; flight attendants remain professional, focused on safety.

So, the next time you hear a warm greeting, know it’s part of a larger safety protocol to ensure everyone’s well-being on board.
