  • Pack light and skip checked bags—when flying with budget airlines, traveling with just a carry-on can often save you money. To maximize space, opt for travel-sized toiletries, wear your bulkiest clothing, and plan your outfits carefully. This approach also allows you to bypass the wait at baggage claim upon arrival.
  • Bring your own entertainment—many short-haul flights may not provide in-flight entertainment options. To keep yourself engaged, download TV shows, movies, music, or podcasts ahead of time, and consider bringing a book. Be sure to charge your devices fully 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 before your departure, taking into account potential traffic and security lines.
  • Bring your own snacks and water—pack some snacks and a refillable water bottle to keep hydrated and save money 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 crucial 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 you to select your seat even earlier.
  • Arrive at the airport in plenty of time—aim to arrive at the airport at least 3 hours prior to departure for international flights to ensure you have enough time for 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 acclimating your body clock by setting your watch and adjusting 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 mitigate jet lag.
