  • 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 procedures.
  • Relax at the airport—if you have extra time, take the opportunity to explore the shops, find a coffee shop, or unwind at the gate or in a departure lounge if you have access. Free airport Wi-Fi is generally available.
