However, one area remained that causes problems to the crew, and that is the availability of alcohol on flights (no longer free on some airlines). Eventually there will be times when somebody will go overboard and decide that enough alcohol needs to be added to their system to make them unable to control themselves and then create a fuss. It gets tricky for the crew as to how to handle these passengers, in many cases, they are handed over to security after the plane makes a quick stop-over at the closest airport. However, in this case, the crew had an interesting way of restraining the passenger, they tied him up (link to article):
After a few drinks on flight AI-301 on Wednesday, the passenger allegedly got into a tiff with some crew members and passengers and then tried to hit them and tore the clothes of two attendants, airline sources said. As the incident turned into a major row, the passenger was overpowered by some crew and passengers and tied him up on the seat, they said. This led the captain to consider diverting the flight to Singapore because of the threat posed to the other passengers.In the end, the passenger does get handed over to security for further processing; there is much less patience with passengers who get unruly or misbehave with staff.
