PE Baggage Allowance to India

Having only flown to the US several times in PE my baggage allowance has always been 2 pieces at 32kgs. I am about to fly out to Mumbai in PE and the allowance is only ONE PIECE at 20kgs!!! Does anyone know why and how strict they are about this. We are flying on to Goa and rather than go with the terrible direct charters (we flew Excel last year who were great but they only lasted one season) we are getting less allowance than the premium seats on direct charters.
