Non-availability of aircraft due to maintenance issues has forced Air India to cancel some 60 flights on India-US routes between Nov and Dec.

Air India has cancelled around 60 flights to and from San Francisco, Washington, Chicago, Newark and New York between November 15 and December 31.

Air India, in a statement, said it has cancelled a 'small' number of flights between November and December on account of delayed return of some aircraft from heavy maintenance and supply chain constraints, without naming the destinations.
