Arriving at airports hours early costs travellers time and stress without delivering proportional benefits. Travel expert Gary Leff of View From The Wing argues that missing an occasional flight beats padding every itinerary with excessive buffer time.
The math matters. Standard advice recommends arriving two hours before domestic flights and three hours before international flights. Following this religiously wastes roughly 120 to 180 minutes per trip for most passengers. Over a year, frequent travellers burn dozens of hours in airport lounges and security lines.
The real strategy hinges on what's at stake. A missed connection to a casual beach weekend in Cancun carries minor consequences. Rebooking onto another flight costs time but not the vacation itself. Miss your flight to a wedding in Denver, a conference in Las Vegas, or a non-refundable cruise departure from Miami, and the trip effectively disappears.
Leff's approach separates trips into two categories. Low-stakes travel, where missing the flight merely delays arrival by a day or two, warrants minimal buffer time. Arrive 60 to 90 minutes early for domestic flights. For high-stakes travel, the calculus flips. Non-refundable events, connections with tight layovers, and international trips warrant full buffer compliance.
Travellers should also consider airport efficiency. Atlanta Hartsfield-Jackson or Chicago O'Hare move passengers quickly through security. Smaller regional airports like Bozeman or Santa Fe often have minimal crowds. Flying from New York's LaGuardia during rush hour demands different timing than departing from Denver on a Tuesday morning.
Weather and day-of-week create variance too. Summer Fridays and holiday periods pack terminals. Tuesday and Wednesday departures typically move faster.
The practical application rewards planning. Calculate what a missed flight costs for each trip. Compare that against the dollar value of your time
