Maximize your space by using mini toiletries, wearing your bulkiest clothing, and planning your outfits wisely. This method 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. To keep yourself engaged, download your favorite TV shows, movies, music, or podcasts beforehand, and don’t forget to pack a book. Be sure to charge your devices fully before you board.
  • Arrive at the airport in plenty of time—for both short and domestic flights, it's advisable to reach the airport at least 1.5 to 2 hours prior to 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 get to the airport at least 3 hours before departure for international flights to accommodate check-in, security, and immigration processes.
  • Relax at the airport—if you have some 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 to synchronize your body clock by changing your watch and adjusting your sleep schedule to align with your destination's time zone.
