An Air India Express flight from Pune to Jaipur faced a medical emergency on Tuesday due to a malfunctioning air conditioning system, causing excessive heat in the cabin. As the flight prepared for takeoff, a female passenger nearly fainted, prompting the crew to halt the departure and return to the terminal. Medical personnel attended to her while remaining passengers endured nearly two hours of discomfort before deboarding. Air India Express later stated that the aircraft could not operate due to technical issues and offered rescheduling or refunds. The incident highlights the importance of functional climate control in aircraft, especially during hot weather.
