Maximize space by using mini toiletries, wearing your bulkiest clothing, and efficiently planning your outfits. 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 TV shows, movies, music, or podcasts ahead of time, and consider bringing a book to keep yourself occupied. Remember to fully charge your devices before you board.
  • Arrive at the airport in plenty of time—for even short or domestic flights, it's advisable to arrive at least 1.5 to 2 hours before departure, taking into account potential traffic and 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—make sure to arrive at the airport at least 3 hours before departure for international flights to ensure you have ample time for check-in, security, and immigration.
  • Relax at the airport—if you have 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. Most airports offer free and accessible Wi-Fi.
  • Adjust to the new time zone mid-flight—begin syncing your body clock by setting your watch and modifying your sleep schedule to align with your destination's time zone.
