Let’s face it, the holidays are never fun for air travelers, especially going through airport security. For starters, too many first time flyers, or folks who only travel by air once a year. And lots of confusion as to what you can and cannot bring through TSA checkpoints.

First, please don’t wrap gifts, because if the TSA can’t identify what’s inside, you’ll have to unwrap it. And if you still insist on wrapping presents, don’t use metallic wrapping paper. And even the cutest present, if it contains more than 3.1 ounces of liquid will be confiscated, and that includes those kitschy snow globes. And you can forget cranberry sauce or spreadable cheese as well.

Then, put a tracking device in your luggage. Need convincing before buying one? Then consider this, last year, U.S. airlines mishandled approximately 3.7 million bags.
