Optimize your packing by including mini toiletries, wearing your heaviest clothing, and coordinating outfits effectively. This strategy also helps you avoid the hassle of waiting at baggage claim upon arrival.

• Arrive at the airport in plenty of time—even for short or domestic flights, it’s advisable to arrive at least 1.5 to 2 hours before your departure. Be sure to account for traffic and potential security lines.
• Bring your own snacks and water—pack some snacks and a refillable water bottle to stay hydrated and save money while at the airport.

• Arrive at the airport in plenty of time—aim to reach the airport at least 3 hours before departure for international flights to accommodate check-in, security, and immigration procedures.
• Relax at the airport—if you have extra time, explore the shops, grab a coffee, or unwind at the gate or in a departure lounge if you have access. Airport Wi-Fi is usually free and readily available.
• Adjust to the new time zone mid-flight—begin syncing your body clock by changing your watch and adjusting your sleep schedule to align with your destination's time zone. Try to sleep or stay awake during the flight according to the local time of your arrival to help minimize jet lag.
