Oh, was OP talking about Jet Airways? Yeah, that airline is practically dead, but there are plenty of other carriers flying to and from India.
I thought his question was about Air Canada cancelling flights a few weeks back due to the geopolitical situation. Those flights are back on.
Air India has cancelled a couple of flights to the UK because of airspace restrictions, but I think those were only to Birmingham (Delhi - Birming. and Amritsar - Birming).
There's definitely no widespread issue with flights to India right now.
