Maximize space by using mini toiletries, wearing your bulkiest clothing, and planning versatile outfits. This strategy also helps you avoid the wait at baggage claim upon arrival.
  • Bring your own entertainment—many short-haul flights might 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 engaged. Remember to fully charge your devices before you board.
  • Arrive at the airport in plenty of time—for short or domestic flights, it’s wise to arrive at least 1.5 to 2 hours before departure, taking into account potential traffic and security lines.

  • Arrive at the airport in plenty of time—aim to arrive at the airport at least 3 hours before your departure for international flights to accommodate check-in, security, and immigration procedures.
  • Relax at the airport—if you find yourself with extra time, take the opportunity to explore the shops, grab a coffee, or unwind at the gate or in a departure lounge if you have access. Airport Wi-Fi is generally free and available.
  • Adjust to the new time zone mid-flight—begin syncing your body clock by changing your watch and modifying 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 reduce jet lag.
