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 you have enough time for check-in, security, and immigration processes.
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.
