Finding the right balance between arriving at the airport and passing through security is crucial to avoid unnecessary waiting or missing a flight.
Airport security opening times vary around the world, with some airports open 24/7 and others opening as early as 02:30.
Factors to consider when deciding how early to arrive at security include airport size, time of day, special assistance needs, and access to airport facilities like lounges. Airlines generally recommend arriving two to three hours before departure.
