  • Pack light and skip checked bags—with budget airlines, traveling with just a carry-on often saves you money. Maximize space by using mini toiletries, wearing your bulkiest clothing, and planning your outfits efficiently. This approach also helps you avoid the hassle of waiting 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 occupied. Remember to charge your devices fully before you board.
  • Arrive at the airport in plenty of time—for short or domestic flights, it's advisable to arrive at least 1.5 to 2 hours prior to departure to account for 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.

  • Select your seat in advance—for longer flights, choosing the right seat is essential for comfort. Full-service airlines typically allow you to select your seat for free once online check-in opens, which is generally 24–48 hours prior to your flight. Some airlines may even provide seat selection sooner 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 to accommodate check-in, security, and immigration processes.
  • Relax at the airport—if you have some 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 typically free and readily available.
  • Adjust to the new time zone mid-flight—begin to sync your body clock by changing your watch and sleep schedule to align with your destination's time zone. Try to sleep or stay awake during the flight according to the local time at your arrival destination to help minimize jet lag.
