-- Flying home after Thanksgiving? After you recover from your turkey coma, you may want to pack your Uncle John's famous mashed potatoes into your checked luggage, or they may be taken away from you at a TSA checkpoint if you try to carry them on.
So what foods can you bring? Check out the TSA-approved list.
Traditional Thanksgiving Items You Can Bring in Your Carry-On Bags
Mashed Potatoes (uncooked, instant mix)
Pies (may be subject to additional screening, depending on what kind of pie it is)
Traditional Thanksgiving Items You Should Pack in Your Checked Bags
Mashed Potatoes (cooked)
Sweet Potatoes (i.e.: casseroles, etc)
Carving Knife (Yes, people really pack these in their carry-ons!)
So in Summary:
If it's more than 3.4 ounces and you can spill it, spray it, spread it, dump it or pour it, it's best to pack it in your checked baggage, or you risk it getting chucked into the garbage at security. Then Grandma won't be mad at you for throwing away perfectly good gravy.
