Tips for short-haul flights to Mount Prospect

  • Pack light and skip checked bags—when flying with budget airlines, traveling with just a carry-on is often more economical. Maximize your space by using mini toiletries, wearing your heaviest clothing, and planning your outfits wisely. This approach also helps you avoid the wait at baggage claim upon arrival.
  • Bring your own entertainment—short-haul flights frequently lack in-flight entertainment options. To keep yourself occupied, download your favorite 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 advisable to arrive at least 1.5 to 2 hours prior to departure, taking into account 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.

Tips for long-haul flights to Mount Prospect

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 often allow free seat selection once online check-in opens, typically 24–48 hours before your flight. Some airlines may provide the option to select seats even earlier than this.
  • Arrive at the airport in plenty of time—plan to arrive at the airport at least 3 hours prior to departure for international flights to accommodate check-in, security, and immigration processes.
  • Relax at the airport—if you have extra time, take the opportunity to browse 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 changing 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 at your arrival destination to help minimize jet lag.
