  • Arrive at the airport in plenty of time—make sure to arrive at least 3 hours prior to departure for international flights to accommodate check-in, security, and immigration procedures.
  • Relax at the airport—if you have some extra time, take the opportunity to browse the shops, visit a coffee shop, or unwind at the gate or in a departure lounge if you have access. Most airports offer free and accessible Wi-Fi.
