I've searched online (google) but can't seem to find a good answer. Are there any travel insurance policies that will reimburse (or ideally pay for a new flight) if you miss your flight.

Domestic flight within India (booked stand-alone) from Jaipur to Delhi. Then international flight Delhi to USA. If I somehow have problems with the flight from Jaipur to Delhi - is there any flight insurance that would ideally pay for a new flight Delhi to USA? That would be better than reimbursing for original flight because a last minute one way ticket would not be cheap.

I know Delhi-USA flight will not volunteer to rebook me because they are not responsible for the Jaipur Delhi leg.

I have tried to minimize risk - flight Jaipur - Delhi (leaves 355pm arrives 455 pm on Sunday) Delhi - USA flight leaves Monday morning at 2 am. There are 3 other flights Jaipur/Delhi after my Air India flight in case of any cancellations. But I'd still fell a bit better if there were a reasonably priced insurance policy I could buy. This doesn't really fall under flight cancellation or delay from what I could tell. Thanks.
