Maximize your space by packing travel-sized toiletries, wearing your bulkiest clothing, and coordinating outfits smartly. This approach also helps you avoid 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 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—even for short or domestic flights, it’s advisable to arrive at least 1.5 to 2 hours prior to departure, taking into account traffic and security lines.
  • Bring your own snacks and water—pack your favorite snacks and a refillable water bottle to stay hydrated and save on costs at the airport.

  • Arrive at the airport in plenty of time—aim to be at the airport at least 3 hours before your international flight departs 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 acclimating your body clock by changing your watch and adjusting your sleep schedule to align with your destination's time zone.
