We've pulled together all the info you need to make your flight a stress-free experience. Follow our tips and you'll be breezing through airport security and having a blast in Yellowstone National Park in no time.What to pack in your hand luggage:

• It's simple — first, pack in your passport, travel docs, cash and medications. Next, you'll want some in-flight entertainment to help pass the time. A juicy book and a tablet crammed with your favorite shows are some wonderful options. If you plan to take a short nap, a quality neck pillow and some noise-canceling headphones will also come in handy. Finally, squeeze in a toothbrush and some cleansing wipes so you'll hop off the plane feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

• While the list of restricted items differs between air carriers, the general rule of thumb is avoid carrying anything flammable, sharp or explosive. This includes knives, scissors, spray paint and fireworks. Sports equipment like baseball bats, and objects that could harm passengers, such as firearms and ammunition, can't come on board with you either.

What to wear on a flight:

• The key to a comfortable flight can be as simple as your choice in clothes. Prepare for changes in temperature by layering up. This will keep you nice and warm if the cabin starts to cool down. Shoes like high heels and sandals are best left in your checked suitcase. Even though they may be your favorites, opt for flat, closed-toed footwear like sneakers. Your feet will thank you later.
• You've probably heard about DVT (deep vein thrombosis), a blood clot condition caused by long periods of inactivity. There's lots you can do to lessen your risk. Wear compression tights or socks, drink lots of water and remember to keep your legs and feet moving. Walk the aisles of the cabin or perform some simple exercises in your seat.

It's simple — be prepared. We've put together some handy tips and tricks for a fuss-free trip through airport security. Look out Yellowstone National Park, here you come:

• Security personnel first need to see that you have a valid ID and boarding pass before anything else. Have them in your hand, ready for inspection.
• Your coat, belt, keys and other items in your pocket, like coins, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them before your turn arrives.
• Your electronic devices like laptops and phones will also need to go on a tray to be scanned. No need to worry though, you'll be back online soon enough.
• Want to bring along your favorite perfume or cologne? No problem. As long as the volume is no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, you can keep it with you on board.
• Choosing your footwear wisely can save you several valuable minutes. Hiking boots are often required to be removed and separately scanned. Slip-on shoes usually aren't.
• Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked luggage. They won't be allowed on board and will be confiscated.
