Tips for short-haul flights to Glen

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, traveling with just a carry-on is often more economical. Maximize your space by packing travel-sized toiletries, wearing your heaviest clothing, and planning versatile outfits. This strategy also helps you avoid the hassle of waiting at baggage claim upon arrival.
  • Bring your own entertainment—short-haul flights frequently lack in-flight entertainment options. To keep yourself engaged, 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 brief or domestic flights, it’s wise to get to the airport at least 1.5 to 2 hours prior to departure, taking into account potential traffic and security lines.
  • Bring your own snacks and water—to stay hydrated and save money at the airport, pack your own snacks and a refillable water bottle.

  • Arrive at the airport in plenty of time—make sure to arrive at least 3 hours before departure for international flights to accommodate check-in, security, and immigration procedures.
  • Relax at the airport—if you have some extra time, take a stroll through the shops, find a coffee shop, or unwind at the gate or in a departure lounge if you have access. Typically, airport Wi-Fi is free and available.
