Sikhs Can Carry Knives on Airplanes in India
That’s what the rules say:
Sikh passengers are allowed to carry Kirpan with them on board domestic flights. The total length of the ‘Kirpan’ should not exceed 22.86 CMs (9 inches) and the length of the blade should not exceed 15.24 CMs. (6 inches). It is being reiterated that these instructions should be fully implemented by concerned security personnel so that religious sentiments of the Sikh passengers are not hurt.
How airport security is supposed to recognize a Sikh passenger is not explained.
