  • Arrive at the airport in plenty of time—even for short or domestic flights, it’s advisable to arrive at least 1.5 to 2 hours prior to departure, taking into account potential traffic and security lines.
  • Bring your own snacks and water—pack your favorite snacks and a refillable water bottle to stay hydrated and save money while at the airport.

  • Arrive at the airport in plenty of time—make sure to arrive at least 3 hours before 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 explore the shops, grab a coffee, or unwind at the gate or in a departure lounge if you have access. Airport Wi-Fi is usually free and readily available.
  • Adjust to the new time zone mid-flight—begin syncing your body clock by changing your watch and adjusting your sleep schedule to align with your destination's time zone.
