  • Arrive at the airport in plenty of time—aim to reach the airport at least 3 hours before departure for international flights to ensure you have enough time for check-in, security, and immigration procedures.
  • Relax at the airport—if you have 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. Airport Wi-Fi is generally free and available.
