I'd think so. If it's a sealed container, then when the flying creature
does whatever it does to fly (flap its wings, levitate, whatever) it's going
to push against the air, which will in turn push against the container,
yielding the right amount of mass for the whole closed system.
Unless the creature is levitating by manipulating the force of gravity, just
because it's flying, it won't change the fact that the entire container
still has the same amount of mass.
(I guess all those science classes I took in college talking about closed
systems finally paid off!)
