Maximize your space by choosing mini toiletries, wearing your bulkiest clothing, and organizing your outfits efficiently. This approach also allows you to avoid the wait at baggage claim upon arrival.
  • Bring your own entertainment—many short-haul flights may not provide in-flight entertainment options. To keep yourself engaged, download TV shows, movies, music, or podcasts ahead of time and consider bringing a book. Don’t forget to 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 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 at the airport.

  • Arrive at the airport in plenty of time—aim to arrive at least 3 hours before departure for international flights to accommodate check-in, security, and immigration processes.
  • Relax at the airport—if you find yourself with extra time, take the opportunity to explore the shops, visit a coffee shop, or unwind at the gate or in a departure lounge if you have access. Most airports offer complimentary Wi-Fi.
  • 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.
