Watch out for wheel chair attendants pretending to be porters and suggesting it would cost 10x the regular porter fare (INR 6000 vs 510) to help offload your bags from the belt and load into your car/Uber.
This happened to me yesterday. I knew this guy was out to scam me (as I was aware of the official rate), so I pretended to play along until we were at the luggage belt at which point I reported him to an airport official (that's when I knew he was a wheel chair attendant). Turns out this has been happening a lot lately!
