Maximize space by using mini toiletries, wearing your bulkiest clothing, and organizing outfits efficiently. This approach also allows you to bypass the wait at baggage claim upon arrival.
  • Bring your own entertainment—many short-haul flights might not provide in-flight entertainment. Download your favorite TV shows, movies, music, or podcasts beforehand, and consider bringing a book to keep yourself entertained. 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 ahead of departure, taking into account traffic and security lines.
  • Bring your own snacks and water—pack some snacks along with a refillable water bottle to stay hydrated and save money at the airport.

  • Arrive at the airport in plenty of time—make sure to arrive at least 3 hours before departure for international flights to accommodate check-in, security, and immigration procedures.
  • Relax at the airport—if you have some extra time, take a moment 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 setting your watch and adjusting your sleep schedule to align with your destination's time zone. Try to rest or stay awake during the flight according to the local time at your arrival destination to help minimize jet lag.
