Maximize your space by using mini toiletries, wearing your heaviest clothes, and coordinating your outfits in advance. This 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. 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—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 conditions and security lines.
  • Bring your own snacks and water—pack your own snacks and a refillable water bottle to stay hydrated and save money at the airport.

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