Maximize your space by packing travel-sized toiletries, wearing your heaviest clothing, and planning your outfits effectively. This approach also allows you to bypass the wait at baggage claim upon arrival.
• Bring your own entertainment—many short-haul flights may lack in-flight entertainment options. Download your favorite TV shows, movies, music, or podcasts ahead of time, and consider bringing a book to keep yourself entertained. Remember to fully charge your devices before you board.
• Arrive at the airport in plenty of time—even for short or domestic flights, it's wise to arrive at least 1.5 to 2 hours prior to departure, allowing for traffic and security lines.

• Arrive at the airport in plenty of time—aim to arrive at the airport at least 3 hours prior to departure for international flights to accommodate check-in, security, and immigration procedures.
• Relax at the airport—if you have extra time, take the opportunity to explore the shops, enjoy a coffee, or unwind at the gate or in a departure lounge if you have access. Airport Wi-Fi is typically free and 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 at your arrival destination to help minimize jet lag.
