Honestly Pran, I am not that surprised! RNC-BSB VB is a bubble route that has been over-hyped.
They should have introduced the HWH-BSB VB which would have been a huge success.
Historically Kolkata has provided the most tourists at BSB and the demand is always substantial.
HWH-BSB...
more... would be a smash hit.
Some guys are advocating for a run via DTO, it will flop even harder there.
RNC has been un-necessarily overhyped by the JH politicians.
It is the capital city of JH but it isn't a huge city.
