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 traffic and security lines.

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 accommodate check-in, security, and immigration procedures.
Relax at the airport—if you have some extra time, explore the shops, grab 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 to sync your body clock by changing your watch and adjusting your sleep schedule to align with your destination's time zone. Aim to sleep or stay awake during the flight according to the local time at your arrival destination to help minimize jet lag.
