Tips for short-haul flights to Merrillville

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. Maximize your luggage space by bringing mini toiletries, wearing your heaviest clothes, and planning your outfits carefully. 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. To keep yourself entertained, download TV shows, movies, music, or podcasts ahead of time, and consider bringing a book. Remember 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 departure, allowing for traffic and security lines.
  • Bring your own snacks and water—pack some snacks and a refillable water bottle to stay hydrated and save on costs at the airport.

Tips for long-haul flights to Merrillville

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

  • Select your seat in advance—for long flights, choosing your seat is crucial for comfort. Full-service airlines often allow free seat selection once online check-in opens, typically 24–48 hours before your flight. Some airlines may permit seat selection even earlier.
  • Arrive at the airport in plenty of time—aim to be at the airport at least 3 hours prior to departure for international flights to ensure adequate time for 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 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 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 during the flight according to the local time upon arrival to help mitigate jet lag.
