Flight attendants pay close attention to passengers as they board, using this brief interaction to make important assessments for safety and comfort throughout the flight. Although these observations happen quickly, they are not meant to judge passengers but rather to ensure everyone’s well-being.
Emilia Ryan told Reader's Digest that cabin crew are "not judging you for it." Instead, these assessments help identify who may need assistance or who could help in an emergency. Duygu Eren Tosya, chief of Turkish Airlines cabin crew, explained to Travel + Leisure: "They are identifying passengers who may be able to assist in an emergency, as well as passengers who may need additional help in an emergency situation, such as an elderly or injured person."
Janice Bridger, a flight attendant sharing her experience on Quora, noted: "I watch for disabilities that may disqualify someone from sitting in the exit row. They need to be able to physically lift a heavy hatch (up to 60 lbs) or open a heavy door (several hundred pounds)." Flight attendants also notice inexperienced travelers. Kimberly Sullivan wrote on Quora: "We can detect if they are experienced customers by the way they board the plane. If they are holding up the aisle and have tunnel vision, we know they are rookie travelers."
