Is there a priority security for domestic? I know there is one for international.

on my last 3-4 flights at DEL T3 (AI/9W), I had to go thru normal security (although the lines weren't long).

i may have missed the priority security or maybe they didn't have any those days as the lines were more or less empty (mine were all international transit and I crossed security around midnight)

all my my flights were in 2016.
