• Bring your own entertainment—many short-haul flights may 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 short or domestic flights, it’s wise to arrive at least 1.5 to 2 hours before departure, taking into account potential traffic and security lines.

Some airlines may permit seat selection even earlier than this.
• Arrive at the airport in plenty of time—aim 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 some 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 available.
