If Lizzie can fly without wings...
seriously, the writers need to watch the first few movies again.
If Lizzie (the little girl in "The Great Fairy Rescue") can fly with a bunch of fairy dust sprinkled on her... doesn't it follow that they don't need wings to fly at all?
Oh, and I just remembered that in the original Tinkerbell movie - "Peter Pan" - all the kids fly with Peter Pan with the fairy dust.
Too many plot holes for my kids to enjoy it.
But they have to keep grinding them out, don't they?
