Tips for short-haul flights to Firth

For quick getaways, efficiency is key. Here is how to make your short-haul journey smoother:

  • Pack light and skip checked bags—when flying with budget airlines, it’s often more economical to travel with just a carry-on. Optimize your packing by using mini toiletries, wearing your heaviest clothing, and coordinating outfits effectively. 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. 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—even for short or domestic flights, it's wise 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 snacks and a refillable water bottle to stay hydrated while saving 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 essential for comfort. Full-service airlines typically allow free seat selection once online check-in opens, usually 24–48 hours before your flight. Some airlines may offer seat selection even earlier.
  • Arrive at the airport in plenty of time—make sure to arrive at least 3 hours prior to 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 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. Aim to sleep or stay awake on the flight according to the local time at your arrival destination to help minimize jet lag.
