Tips for short-haul flights to South River

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 cost-effective to travel with just a carry-on. Maximize space by using mini toiletries, wearing your heaviest clothing, and coordinating your outfits. This approach also spares you from waiting at baggage claim upon arrival.
• Bring your own entertainment—short-haul flights frequently lack in-flight entertainment options. Prepare by downloading TV shows, movies, music, or podcasts ahead of time, and consider bringing a book to keep yourself occupied. Remember to charge your devices fully before you board.
• Arrive at the airport in plenty of time—for short or domestic flights, it's advisable to get to the airport at least 1.5 to 2 hours prior to departure, allowing for traffic and security line delays.
• Bring your own snacks and water—pack some snacks and a refillable water bottle to stay hydrated and save money at the airport.

Full-service airlines often allow free seat selection once online check-in becomes available, typically 24–48 hours before your flight. Some airlines may permit seat selection even earlier.
• Arrive at the airport in plenty of time—be sure to arrive at the airport at least 3 hours prior to departure for international flights. This will give you enough time for check-in, security, and immigration procedures.
• Relax at the airport—if you have extra time, take the opportunity to explore the shops, find a cozy coffee shop, or unwind at the gate or in a departure lounge if you have access. Most airports offer free Wi-Fi that you can easily access.
• 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. Try to sleep or stay awake during the flight according to the local time at your arrival destination to help minimize jet lag.
