• 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 processes.
• 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. Most airports offer free and accessible Wi-Fi.
• Adjust to the new time zone mid-flight—begin syncing your body clock by changing your watch and sleep schedule to correspond with your destination's time zone. Try to sleep or stay awake during the flight according to the local time at your arrival location to help minimize jet lag.
