Delhi to Kuala Lumpur (Daily) starts again in September. The Air India website does allow you to book the route via Delhi, but I suspect the advertising to merely to drum up bookings beyond Delhi.
As you can book nearly any route that AI serve any day, albeit via another airport like Frankfurt on days when there is no direct flight, it appears as if it is daily.
