Save space by using mini toiletries, wearing your heaviest clothing, and planning your outfits wisely. This approach also allows you to bypass the wait at baggage claim upon arrival.

  • 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 prior to departure, taking into account traffic and security lines.
  • Bring your own snacks and water—pack snacks and a refillable water bottle to stay hydrated and save money while at the airport.

  • 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 you to select your seat even earlier.
  • Arrive at the airport in plenty of time—aim to reach 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 find yourself with extra time, take the opportunity to explore the shops, grab a coffee, or unwind at your 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 adjusting your sleep schedule to align with your destination's time zone.
