Save space by using travel-sized toiletries, wearing your heaviest clothing, and planning your outfits wisely. This approach also helps you avoid the hassle of 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 for additional entertainment. 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, taking into account 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 arrive at 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 syncing your body clock by changing your watch and sleep schedule to align with your destination's time zone. Try to either sleep or stay awake during the flight according to the local time at your arrival destination to help minimize jet lag.
