DecodeFlightRoute Api issue

Hi,

For some flights like India jet airways airline this api not giving any response. So how to get decode path for that type airlines.

Please help.

Not all flight routes can be successfully decoded by this function, particularly if the flight is not entirely within the continental U.S. airspace, since this function only has access to navaids within that area.

is any other api provide for decode that airlines?

I am not aware of an api that has the routes decoded for this airline.
