Cathay/Dragon air free baggage allowance is 20KG for Economic class, but my experience 2 weeks ago in Heathrow tells you can put not more than around 24KG.
Cathay/Dragon extra bag charge is based on weight. It charges US$20 per KG from China(ZONE1) to Delhi(ZONE2), which means the extra bag costs you $460, around half of your ticket price
