According to the Civil Aviation Passenger and Luggage Domestic Transportation Rules of China promulgated by the General Administration of Civil Aviation, the elderly over 70 years old must hold the certificate issued by the hospital at or above the county level to fly.
1. It is also reasonable for airlines to require 70-year-olds to provide health certificates. Although the Civil Aviation Administration of China has not clearly stipulated whether the elderly should show the certificate of "suitability for flight", it seems to have become an established "rule" that the elderly need to show relevant certificates when purchasing tickets.
2. At present, China Southern Airlines, China Eastern Airlines, Shanghai Airlines and other airlines have made it clear that as long as family members recognize that the elderly are healthy and suitable for flying, they do not need hospital certificates. Airlines such as Air China, Shenzhen Airlines and Hainan Airlines all said that the elderly must show the certificate issued by the hospital to buy air tickets. 3. Companies also have different standards for how old the elderly need to be to open a "certificate". Among them, Air China requires the elderly over 80 to show the certificate of "suitable for flying"; Shenzhen Airlines and Hainan Airlines require people over 70 to issue certificates.
4. A few domestic airlines (China Southern Airlines) adopt a humanized approach: before purchasing tickets, the conductor will ask the elderly about their physical condition and tell them when they can't fly. After arriving at the airport, if the staff find that the elderly are in poor health, they will inform the airport medical staff to check them. Once it is confirmed that the elderly are not suitable for boarding, the staff of the company will advise the elderly to give up boarding. It is understood that in 2007, the EU issued a regulation prohibiting all airports and airlines in the EU from discriminating against the elderly and the weak.
When it is safe, passengers sitting in the emergency exit of the plane should be absolutely careful not to lift the handrail out of curiosity, or the plane will land or crash. Passengers can't joke that this is a bomb, otherwise they will be detained and bear the huge expenses incurred. After you sit down, the program on the plane begins.
