Tips for short-haul flights to St. Marys

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 space by using mini toiletries, donning your bulkiest clothing, and coordinating your outfits effectively. This strategy also helps you avoid the wait at baggage claim upon arrival.
  • Bring your own entertainment—short-haul flights often 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 brief or domestic flights, it’s advisable to get to the airport at least 1.5 to 2 hours before your departure time, taking into account potential traffic and security lines.
  • Bring your own snacks and water—pack some snacks and carry a refillable water bottle to stay hydrated and save money while at the airport.

Tips for long-haul flights to St. Marys

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 typically allow free seat selection once online check-in opens, usually 24–48 hours before your flight. Some airlines may provide the option to select seats even earlier.
  • Arrive at the airport in plenty of time—aim to be at the airport at least 3 hours before your departure for international flights. This will give you enough time for check-in, security, and immigration procedures.
  • Relax at the airport—if you have some extra time, take the opportunity to explore the shops, enjoy a coffee, or unwind at the gate or in a departure lounge if you have access. Airport Wi-Fi is generally free and widely available.
  • Adjust to the new time zone mid-flight—begin to sync your body clock by setting your watch and modifying your sleep schedule to align with your destination's time zone. Try to rest or stay awake during the flight according to the local time at your arrival location to help minimize jet lag.
