Maximize your space by using mini toiletries, wearing your bulkiest clothing, and planning your outfits carefully. This strategy also helps you avoid the hassle of waiting at baggage claim upon arrival.
  • Bring your own entertainment—many short-haul flights may not provide in-flight entertainment. To keep yourself entertained, download TV shows, movies, music, or podcasts ahead of time, and consider bringing a book. Remember to charge your devices fully 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 your departure, allowing for traffic and security lines.
  • Bring your own snacks and water—pack snacks and a reusable water bottle to stay hydrated and save money 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 account for check-in, security, and immigration procedures.
  • Relax at the airport—if you have some extra time, feel free 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 sleep schedule to align with your destination's time zone. Aim to sleep or stay awake during the flight according to the local time of your arrival to minimize jet lag.
