Live flight tracking gives you a real-time map to any flight's position, but arriving to an airport terminal on time to pick someone up is a different task. Discover which live flight-position data can actually help, timing on the arrival terminal's specific curbside pickup rules, and where O'Hare says you should wait to be picked up.
How Flight-Tracking Data Is Built
Flight tracking has been feasible for decades, but the use of standardized signal broadcasts and international databases make it much more specific in 2026. The aircrafts themselves broadcast position data while in flight. ADS-B, Automatic Dependent Surveillance-Broadcast, is the system that transmits live position and velocity data. The FAA provides aeronautical data through its portal.
ADS-B is broadcast directly from each aircraft. It can include altitude, ground speed, heading, vertical rate, and a unique identifier - ADS-B sends out this data once per second. Don't mistake ADS-B as where they'll arrive to the terminal to pick up. Flight tracking data is also pulled from the airlines and airports themselves. Originally from scheduled/gate/terminal/timing data.
This is especially useful for knowing where exactly in the terminal the plane is, or what time it's expected to get there. It is not the same information as live position data. If you want to know the specifics in English, like gate, terminal, baggage carousel, or the airline’s official estimated departure or arrival, you need to rely on airline/airport data sources.
Since you want to know specifically where to arrive, look to the airlines and airports. None of this tracking information can show you that, but the airlines and airports provide information using ADS-B and other sources. The official data is available - see the FAA's data portal or FlightAware's description of their service. They combine live aircraft-position data, ADS-B and Mode S receivers, and multiple government air traffic control sources.
When the plane lands on the runway, it doesn't mean the passenger will necessarily show up right after. There are still steps before they reach the curb.
From Wheels to the Curb
When a plane lands, it doesn't mean that they'll necessarily leave the airport right after. When you see the plane land on the runway, it hasn't come to the gate yet. After it lands, it has to find out which gate to be assigned to. This is a gate that is open, where they can park and let the passengers unload. This can take a long time, as there are limited gates, and a lot of flights stacked up landing around the same time. When you see an arrival time for the flight, this isn't the point it will leave, this is when it officially lands and is at the airport. They might not even have a gate added to their traveler booking at this point. Gate assignment is usually happening after the flight lands, depending on how busy the airport is. The passengers can't deboard until the plane is parked and the gate is secure.
After the flight is parked, passengers actually still can't leave the plane for usually about 10-15 minutes. This is because the plane needs to be cleaned, restocked, refueled, and inspected. Then passengers can leave, but even then, getting out of the airport isn't that fast. From the gates, you may need to walk down a hallway for a while, or take an escalator. Then you get to the baggage claim, which can vary drastically in time. Passengers need to get off the plane and get their luggage. Afterwards, everyone has to leave the terminal. The terminal is a split area between arriving on one side, and departing on the other. Passengers get their luggage, and there's usually a long barriered off area to walk through to get out the door and to where the pickup curbs are. This baggage and customs area can take a while to get through. Passengers waiting to leave have to wait for everyone that is coming in from the flight to get their bags and be processed. The number of people can drastically sway how long it will take to get to your luggage and through the terminal.
