Some airlines may allow seat selection even earlier than this.
• Arrive at the airport in plenty of time—aim to arrive at least 3 hours before your departure for international flights, allowing sufficient 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 your gate or in a departure lounge if you have access. Airport Wi-Fi is generally free and readily available.
