  • Bring your own entertainment—many short-haul flights may lack in-flight entertainment options. Download your favorite TV shows, movies, music, or podcasts ahead of time, and consider bringing a book to keep yourself occupied. Remember to fully charge your devices before you board.

  • Arrive at the airport in plenty of time—make sure to arrive at the airport at least 3 hours before 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. Free airport Wi-Fi is generally available.
