  • Pack light and skip checked bags—with budget airlines, traveling with just a carry-on is often more cost-effective. Maximize space by using mini toiletries, wearing your bulkiest clothing, and planning your outfits wisely. This strategy also allows you to bypass the wait at baggage claim upon arrival.
  • Bring your own entertainment—many short-haul flights may lack in-flight entertainment options. To keep yourself engaged, download TV shows, movies, music, or podcasts ahead of time, and consider bringing a book. Remember to fully charge your devices 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, taking into account potential traffic and security lines.
  • Bring your own snacks and water—pack your favorite 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 allow free seat selection once online check-in opens, typically 24–48 hours before your flight. Some airlines even offer this option earlier.
  • Arrive at the airport in plenty of time—aim to reach the airport at least 3 hours before departure for international flights to allow sufficient time for check-in, security, and immigration procedures.
  • Relax at the airport—if you have extra time, take a moment to explore the shops, find a coffee shop, or unwind at the gate or in a departure lounge if you have access. Most airports offer free and accessible Wi-Fi.
  • Adjust to the new time zone mid-flight—begin syncing 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.
