Yes, flight attendants undergo rigorous medical and psychological training to manage various in-flight emergencies, including panic attacks and severe anxiety. In 2026, aviation safety standards require cabin crew to be proficient in "Psychological First Aid," which involves techniques to de-escalate high-stress situations, utilize calming communication, and identify the physical symptoms of a panic attack versus other medical issues like heart attacks or hypoxia. They are taught to move a distressed passenger to a quieter area if possible, provide supplemental oxygen if necessary, and use a firm yet empathetic tone to help the individual regain control of their breathing. Furthermore, most modern aircraft are equipped with MedLink or similar services, allowing crew members to consult with ground-based doctors in real-time for guidance on administering sedatives from the onboard Emergency Medical Kit (EMK) if the situation becomes unmanageable or poses a safety risk to the flight.
