Cost of carrying an infant under 2 is usually 10% of full adult seat cost, and not a discounted one.
Personally, I have now flown twice with my young one and actually purchased cheapest tickets possible for all of us, ie, three seats, our UK carrier is offering a decent deal currently, four seats costing less than HK$20,000, if you use a travel system, this really is the best way to go, as you can have a travel seat for the child and a bassinet.
Hope this helps, but it really does depend on what your budget is.
