Bring your own entertainment—many short-haul flights do not provide in-flight entertainment options. Download your favorite TV shows, movies, music, or podcasts ahead of time, and consider bringing a book to keep yourself entertained. Remember to fully charge your devices before you board.
Arrive at the airport in plenty of time—for even short or domestic flights, it's wise to arrive at least 1.5 to 2 hours prior to departure, taking into account traffic and security lines.
Bring your own snacks and water—pack snacks and carry a refillable water bottle to stay hydrated and save money while at the airport.

Arrive at the airport in plenty of time—aim to arrive at the airport at least 3 hours prior to departure for international flights to ensure ample time for check-in, security clearance, and immigration procedures.
Relax at the airport—if you find yourself with extra time, take the opportunity to explore the shops, grab a coffee, or unwind at your gate or in a departure lounge if you have access. Airport Wi-Fi is generally free and available.
Adjust to the new time zone mid-flight—begin to sync your body clock by changing your watch and adjusting your sleep schedule to align with your destination's time zone. Try to sleep or stay awake during the flight according to the local time at your arrival destination to help minimize jet lag.
