Maximize space by using mini toiletries, donning your bulkiest clothing, and planning your outfits wisely. 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 beforehand, and consider bringing a book to keep yourself entertained. Make sure to fully charge your devices before you board.
  • Arrive at the airport in plenty of time—for even short or domestic flights, it's advisable to arrive at least 1.5 to 2 hours prior to 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.

Flying long-haul sometimes requires extra planning to ensure a comfortable journey:

  • Select your seat in advance—for longer flights, choosing your seat is essential for comfort. Full-service airlines often provide free seat selection once online check-in begins, typically 24–48 hours before your flight. Some airlines may allow seat selection even earlier than this.
  • Arrive at the airport in plenty of time—make sure to arrive at the airport at least 3 hours before departure for international flights. This will give you ample time for check-in, security, and immigration procedures.
  • Relax at the airport—if you find yourself with extra time, consider browsing the shops, grabbing a coffee, or unwinding at the gate or in a departure lounge if you have access. Airport Wi-Fi is generally available for free.
  • 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 sleep or stay awake during the flight according to the local time of your arrival to help minimize jet lag.
