  • Arrive at the airport in plenty of time—make sure to arrive at least 3 hours before departure for international flights, allowing sufficient time for check-in, security, and immigration.
  • Relax at the airport—if you have 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 provide free Wi-Fi for your convenience.
