Since the meetings are of Sikhs, so usually Sikhs are present there.
Many Sikhs do not fly for this reason. Sikhs who do fly often remove their kirpan, since they are not flying as a Sikh representative. There have been incidents of Sikhs not attending meetings at government buildings (White House, EU Parliment) due to the security requirements. Since they were attending as representatives of the Sikh faith, they declined to participate rather than removing their kirpans.
