Tips for short-haul flights to Grand Isle

  • Pack light and skip checked bags—for budget airlines, traveling with just a carry-on is often more economical. Maximize space by using mini toiletries, wearing your bulkiest attire, and planning your outfits carefully. This strategy also helps you avoid the hassle of waiting at baggage claim once you arrive.
  • Bring your own entertainment—many short-haul flights may lack in-flight entertainment options. To keep yourself engaged, 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 traffic conditions and security lines.
  • Bring your own snacks and water—pack your favorite snacks and a refillable water bottle to stay hydrated and save money while at the airport.

Some airlines may even permit seat selection earlier than this.
  • Arrive at the airport in plenty of time—aim to arrive at the airport at least 3 hours before your departure for international flights to accommodate check-in, security, and immigration procedures.
  • Relax at the airport—if you have 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. Airport Wi-Fi is usually free and readily available.
  • Adjust to the new time zone mid-flight—begin to align your body clock by changing your watch and modifying your sleep schedule to coincide 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.
