Yes, you pay to fly the 5 year old. Are you flying Internationally or domestically? Try www.sidestep.com or www.kayak.com or vayama.com compare these to the direct airline's web site and that's about the best you'll do in the USA. If you're flying internationally, that might be different as you can sometimes get consolidated air to europe, asia, etc.
