  • Pack light and skip checked bags—with budget airlines, traveling with just a carry-on is often more economical. Maximize space by using mini toiletries, wearing your heaviest clothing, and planning versatile outfits. This strategy also helps you avoid the wait 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 to keep yourself engaged. Remember to fully charge your devices 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 prior to departure, taking into account traffic and security lines.
  • Bring your own snacks and water—pack some snacks along with 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 complimentary seat selection once online check-in opens, typically 24–48 hours before your flight. Some airlines may allow seat selection even earlier.
  • Arrive at the airport in plenty of time—aim to be at the airport at least 3 hours before departure for international flights to ensure you have enough time for check-in, security, and immigration procedures.
  • Relax at the airport—if you find yourself with 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 setting your watch and adjusting your 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.
