  • Arrive at the airport in plenty of time—aim to be at the airport 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, enjoy a coffee, or unwind at the gate or in a departure lounge if you have access. Airport Wi-Fi is generally free and readily available.
  • Adjust to the new time zone mid-flight—begin synchronizing your body clock by setting your watch and modifying your sleep schedule to align with your destination's time zone.
