5. Bring Your Own Water Bottle
The best way to fight jet lag is to drink plenty of water. That said, unless you're in an area where tap-water quality is questionable, paying $5 for a bottle of water after clearing security feels like a plain old rip-off. Bring a used, empty, crushed (to save space) plastic bottle with the cap attached. After security, forcefully blow air into the bottle to re-inflate it, and refill it at any fountain or bathroom faucet. If you use a canteen or reusable water bottle that can't be crushed, remove the top and send it through airport security open so agents can see that it's empty.
6. Prep as You Go
It's always astounding when travelers complain about waiting in an airport security line only to step up to the plate and delay everyone while they try to remove their coat, empty their pants pockets and take-off their boots at the last possible second — and all at the same time. Use your wait time as prep time. Keep your passport or ID and boarding pass in hand, but keep your shoes on until just before it's your turn — those floors are cold! Some major U.S. airports now have security lanes for "expert" and "casual" travelers and a special lane for "family/medical liquids." Choose the lane that best suits you.
7. Talk to the TSA
The TSA has special procedures for travelers with metal implants or prosthetics and those who must carry diabetes kits or other liquid medicines with them. Once you've checked in with your airline, and you're ready to go through security, tell a TSA employee about any special circumstances. They will direct you to the appropriate officer for individualized screening.
8. Look Into Pre-Screening Programs
The TSA has already implemented several programs in various domestic airports — with more being added each year — that enable frequent travelers to undergo a pre-screening process. If, after this process, you're considered a low-security-risk traveler, you'll be eligible for expedited airport screening. This means you won't need to remove articles of clothing or shoes or take your 3-1-1 bag or laptop out of your carry-on at security checkpoints.
