In 2026, the general rule remains that airlines will not hold a plane for individual connecting passengers, as doing so creates a "domino effect" that can disrupt thousands of other travelers and cause the flight crew to exceed their legal duty hours. However, a captain may choose to hold a flight for 10 to 15 minutes if a large group of 20 or more passengers is arriving from a slightly delayed inbound flight and the departure gate is not strictly needed for another arrival. Under U.S. DOT tarmac delay rules, once you are on the plane, the airline must begin moving you to a safe deplaning point if the delay exceeds 3 hours for domestic or 4 hours for international flights. For missed connections, modern airline apps now automatically rebook you on the next available flight, often before your original delayed flight has even landed, providing a digital "safety net" for travelers.
