There are so many possibilities for what to do with the Quetz platform saddle. For example You could make a flying home which, if set up correctly, can fit a bed, a forge, a smithy, crop plots on the roof and a pen for one medium sized Dino.

You could make a bomber Quetz that would drop dodos with C4, or a gunship with Dilos and Velonasaurs, or even one giant pen to carry and airdrop Rexes.
