Love took a long flight for a man whoproposed to his girlfriend aboard an Indigo airline flight.In a video of the incident that has gone viral, the passenger can be seen making the proposal using internal announcement system aboard a Indore-Goa flight on May 20.The clip showed the woman walking up to him and the latter, in a hat tip to countless romantic celluloid scenes, kneeling and offering his ladylove a rose.The airline staff, in an apparent show of support for the man, can be seen holding placards on the aerobridge with "will you marry me?" written on them.The romantic gesture, however, allegedly falls foul of the guidelines issued by the Directorate-General of Civil Aviation (DGCA).Indore Airport Director Aryama Sanyal told PTI that the incident took place aboard an IndiGo Airlines Indore-Goa flight.She said that the man had first proposed to his girlfriend on the aerobridge leading to the plane, and later, after obtaining permission from the airline staff, used the internal announcement system.Sanyal said that the incident happened before the plane took off and requested that it be seen in a "positive" manner."If a person is proposing to someone at the aerobridge, then there is no need to take permission from the airport authorities. However, for using the internal announcement of the plane, the nod of the flight's captain must have been taken," she said.The Civil Aviation Requirements (CAR), issued in 2010, state that "the public address system and interphone system are tools for relaying safety information".
