More Free Flights?

We took Evan on seven round trip flights before his second birthday.  It was great to be able to travel so much with him without paying for a ticket for him.  Tonight as we were unpacking from our weekend in Rhode Island, Evan gave me a good idea for a way to get a few more free flights.  Just pack him IN the suitcase!  He looks pretty happy, don't you think?  Think it would work?
