Maximize space by using mini toiletries, wearing your bulkiest clothing, and planning versatile outfits. This also allows you to bypass the wait at baggage claim upon arrival.
  • Bring your own entertainment—short-haul flights frequently 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 entertained. Remember to charge your devices fully before boarding.
  • Arrive at the airport in plenty of time—for short or domestic flights, it’s advisable to arrive at least 1.5 to 2 hours before your departure, allowing extra time for traffic and security lines.
  • Bring your own snacks and water—pack some snacks and a refillable water bottle to stay hydrated and save money at the airport.

  • Select your seat in advance—for longer flights, choosing your seat is essential for comfort. Full-service airlines may allow free seat selection once online check-in begins, typically 24–48 hours before your flight. Some airlines may offer the option to select your seat even earlier.
  • Arrive at the airport in plenty of time—make sure to arrive at the airport at least 3 hours prior to departure for international flights to accommodate check-in, security, and immigration procedures.
  • Relax at the airport—if you have some extra time, take the opportunity to browse the shops, grab a coffee, or unwind at the gate or in a departure lounge if you have access. Most airports provide free and accessible Wi-Fi.
  • Adjust to the new time zone mid-flight—begin syncing your body clock by changing your watch and adjusting your sleep schedule to align with your destination's time zone. Aim to either sleep or stay awake during the flight according to the local time at your arrival destination to help minimize jet lag.
