Airport hacks that'll save you time, money, and sanity

After 40+ countries, here's what I've learned:

• Download your airline's app: You'll get gate changes, delays, and cancellations before airport screens update

• Take a photo of your luggage before checking it in. If it gets lost, you have proof of what it looks like

• Bring an empty water bottle: Fill it after security instead of paying for airport water

• Screenshot your boarding pass: WiFi dies, phones glitch, apps crash. Always have an offline backup

• Check if your credit card gives lounge access: Many premium cards include Priority Pass or lounge visits you didn't even know about

• Wear your bulkiest items on the plane: This saves luggage space and weight. Jackets, boots, hoodies. Wear them, don't pack them
