Getting confirmed seat from pune-jbp/ald is very difficult and takes a well atleast 2 months in advance reservation.
But if in urgent,then before going for tatkal or PT, kindly check availability for GNWL i.e pune-ara/bxr/pnbe. Majority of time GNWL remains less crowded and getting confirmed seats are easier,specially in sleeper class. But this is applicable only for non-festive season. During the month of oct-nov and march, this train sometime even gets 500-600 waiting in sleepers.
And AC class is always full through out the year.
