  • Arrive at the airport in plenty of time—make sure to arrive at the airport at least 3 hours before departure for international flights to account for check-in, security, and immigration procedures.
  • Relax at the airport—if you have some extra time, take a moment to browse the shops, find a coffee shop, 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 acclimating your body clock by setting your watch and adjusting your sleep schedule to align with your destination's time zone.
