Tips for short-haul flights to Harrisburg

Optimize your packing by using mini toiletries, wearing your heaviest clothing, and coordinating outfits effectively. 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 occupied, 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 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 some snacks and a refillable water bottle to stay hydrated and save money while at the airport.

• Arrive at the airport in plenty of time—aim to reach the airport at least 3 hours before departure for international flights to accommodate check-in, security clearance, and immigration procedures.
• Relax at the airport—if you have some 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. Most airports offer free Wi-Fi that is readily available.
• Adjust to the new time zone mid-flight—begin aligning your body clock by changing your watch and adjusting your sleep schedule to reflect your destination's time zone. Try to sleep or stay awake during the flight according to the local time of your arrival to help minimize jet lag.
