ARE YOU ALLOWED TO BRING THESE ITEMS ON THE PLANE?

You can bring the baby powder, wipes, and the medication but they won't allow any food or drinks through security. After you are through security there will be shops to buy the candies and things. A lot of the shops will actually have raisins and gummy bears. On a side note, I would reccomend buying gum or a candy to suck on to prevent your ears from popping while taking off and landing.
