Air India’s flight to London, scheduled to depart from Ahmedabad on Tuesday afternoon, was cancelled due to “operational issues”, an airport official said. The cancellation came just days after a tragic crash involving the same route killed over 270 people on June 12.

Air India flight AI171, a Boeing 787-8 carrying 242 people, crashed after taking off from Ahmedabad on its way to London.

A 1944 global aviation pact, and the principle of shared air safety, explains the foreign presence at the AI 171 crash site
