Maximize space by using mini toiletries, wearing your heaviest clothing, and coordinating outfits wisely. This approach also helps you avoid the hassle of waiting 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 don’t forget to bring a book for additional entertainment. Ensure your devices are fully charged before you board.
• 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 prior to departure, taking into account potential traffic and security lines.
• Bring your own snacks and water—pack your own snacks and a refillable water bottle to stay hydrated and cut down on expenses at the airport.

• Arrive at the airport in plenty of time—make sure to arrive at the airport at least 3 hours before departure for international flights, allowing sufficient time for check-in, security, and immigration processes.
• Relax at the airport—if you find yourself with extra time, consider exploring the stores, enjoying a coffee, or unwinding at the gate or in a departure lounge, if accessible. Free airport Wi-Fi is usually available for your convenience.
• Adjust to the new time zone mid-flight—begin syncing your body clock by setting your watch and adjusting your sleep schedule to align with your destination's time zone. Aim to sleep or stay awake during the flight according to the local time of your arrival to help minimize jet lag.
