• 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 for added enjoyment. Be sure 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 get to the airport at least 1.5 to 2 hours before your departure, taking traffic and security lines into account.

Some airlines even provide seat selection earlier than this.
• Arrive at the airport in plenty of time—make sure to arrive at the airport at least 3 hours prior to departure for international flights to accommodate check-in, security, and immigration processes.
• Relax at the airport—if you have some extra time, take a moment 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 usually available for free.
