Tips for short-haul flights to Key West

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

  • Pack light and skip checked bags—with budget airlines, it's often more economical to travel with just a carry-on. Maximize space by using mini toiletries, wearing your bulkiest clothes, and efficiently planning your outfits. This approach also allows you to bypass the wait at baggage claim upon arrival.
  • Bring your own entertainment—many short-haul flights might not provide in-flight entertainment options. Download your favorite TV shows, movies, music, or podcasts ahead of time and consider bringing a book to keep yourself entertained. 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 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 stay hydrated and save money while at the airport.

Flying long-haul sometimes requires extra planning to ensure a comfortable journey:

  • 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 begins, which is generally 24–48 hours before your flight. Some airlines even permit seat selection earlier than this.
  • Arrive at the airport in plenty of time—make sure to get to the airport at least 3 hours before your international flight departs to accommodate 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. Most airports offer free Wi-Fi for your convenience.
  • Adjust to the new time zone mid-flight—begin synchronizing your body clock by changing 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 of your arrival to help minimize jet lag.
