looking at the winter schedule i can confirm to you that the aircraft is an old 320 with all economy seating, however trying to book a seat on the flight on any date past 4th nov (thats the date when this flight is being separated from jdh) it is showing availability in executive and showing equipment as a 319. on that particualr day what equipment you end up having is pretty dicey because i have been seeing lots of last mimute equipment change lately. speaking to a commercial guy in bbi once, i had asked him what did they do when the business class pax shows up with business ticket on an all economy a/c, he had said that they give them the first 2/5 rows as applicable, keep the middle seat empty and he also mentioned that they provide with an upgrade voucher for use on next flight.

i know of later instances where the first row and middle seat empty was followed, however, i am not aware of any other instance of upgrade voucher.

with all the old 320's converted to all economy, they have managed to get more seats, however with IT not flying, i think its not worth it to convert so many a/c's to all economy. atleast 2 rows of J should be there. am aware of a lot of sectors where there is no J traffic, but knowing how air india does its movement of a/c invariably a/c end up on sectors with strong J requirement and no seats.
