Arrive at the airport in plenty of time—aim to be 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 the opportunity to browse the shops, grab a coffee, or unwind at the gate or in a departure lounge if you have access. Most airports offer free Wi-Fi for your convenience.
Adjust to the new time zone mid-flight—begin syncing your body clock by changing your watch and adjusting your sleep schedule to align with your destination's time zone. Try to either sleep or stay awake during the flight according to the local time of your arrival to help minimize jet lag.
