Flight Status: Which Sources Are Official and How to Read Them

Published Jul 15, 2026 · 6 min read

For an official flight status, check the airline that actually operates your flight first, on its own website or app. The operating airline files the schedule and updates the gate, the time, and any cancellation before anyone else does. Airport arrival and departure boards and independent trackers such as FlightAware and Flightradar24 are useful second checks, not replacements. As of July 2026, when a flight is delayed or cancelled past a set limit, the U.S. Department of Transportation and the European Commission define the thresholds that decide whether you are owed a refund or compensation.

This guide covers scheduled commercial passenger flights, and it leans on United States and European Union rules as examples because both publish their passenger protections in plain terms. It does not cover private aviation, and it is general information, not legal advice. The idea is simple: know which source is authoritative, learn to read what it tells you, and recognize when a delay crosses a line that affects your money.

Start with the airline that operates the flight

The operating airline is the official source for your flight's status. It owns the aircraft, the crew roster, and the gate assignment, so its system changes first, and its app can send a push alert the moment a departure time slips.

Things get confusing with a codeshare, which is one flight sold under several airlines' flight numbers. The airline that flies the plane is the operating carrier; the others are marketing carriers that copy the schedule, sometimes with a lag. When the operating and ticketing airlines differ, your e-ticket and boarding pass show a line reading "Operated by" followed by the operating carrier's name. Check the status on that airline, and use its flight number, since a codeshare partner's number may point to a stale or slightly different schedule.

Which website shows the most accurate flight status?

The operating airline's own site is the most accurate for times and gates, while a large independent tracker is often quicker to confirm the plane is physically in the air. Use them in order. Look at the airline app for the official time and gate, glance at the destination or origin airport's board to confirm the terminal, and open a tracker only if you want to watch the aircraft move or check whether the inbound plane for your flight is running late.

An airport's own website lists live arrivals and departures, usually searchable by airline, flight number, or city. That board is the right tool for questions tied to the building, such as which terminal to use or whether an inbound aircraft has landed yet.

What the flight trackers actually show

Most consumer trackers work off ADS-B, short for Automatic Dependent Surveillance-Broadcast, a system in which an aircraft broadcasts its own GPS position for ground receivers to pick up. The differences between platforms come down to what data they add on top of that signal.

FlightAware states on its data-sources page that it combines a network of more than 30,000 terrestrial ADS-B receivers with official FAA data feeds, EUROCONTROL data, and other government sources, which is why its delay and operational status for U.S. flights often surface early. Flightradar24 describes its coverage as built on a volunteer network of over 35,000 receivers, which tends to make it strong for live aircraft position in busy airspace worldwide. Neither replaces the airline for the official gate and cancellation call.

Reading the status: scheduled, estimated, gate, and delayed

The status page uses a small vocabulary, and it helps to know what each word promises.

• Scheduled is the time filed months ago. It is a plan, not a promise for today.
• Estimated is the airline's current best guess and the number that actually matters as departure approaches.
• Gate can change late, especially after a delay, so recheck it once you are inside the terminal rather than trusting a screenshot from home.
• Delayed or cancelled is the airline's operational decision, and it is the version that counts for rebooking and refunds.

When many flights slip at once, the cause is often weather or air-traffic flow rather than your specific aircraft. In the United States, the Federal Aviation Administration publishes system-wide airport delays and ground stops on its National Airspace System status page, which is a good place to sanity-check whether the whole airport is backed up before you blame one flight.

What are my rights if the flight is delayed or cancelled?

Your rights depend on where you fly and how long the delay runs, and the threshold is a fixed number worth memorizing. Under the U.S. Department of Transportation's refund rule finalized in April 2024 and in effect since October 2024, a flight change counts as significant, and the fare becomes refundable, when a domestic departure or arrival moves by three hours or more, or an international one by six hours or more. The DOT explains these automatic-refund terms on its aviation consumer refunds page.

For flights within, into, or out of Europe on covered carriers, the European Commission's Your Europe portal states that a delay of three or more hours at your final destination can entitle you to compensation of 250 to 600 euros by distance, unless the airline shows extraordinary circumstances such as severe weather. You can read the current terms on the EU's air passenger rights page.

These rules cover the ticket and the airline's duty to rebook you, but they rarely repay a prepaid hotel night or a separate connecting ticket you miss. That gap is where a trip-delay travel insurance policy earns its cost, so read what yours actually pays for before you travel. If a cancellation strands you overnight in a connecting country, it is also worth confirming whether you need a transit visa, one of the details covered in the guide to travel visa requirements to check before you book.

A practical rhythm keeps this manageable. Check the official status the night before, then again two to three hours before departure, and turn on the airline app's alerts so a change reaches you before you leave for the airport. During storms or a major disruption, check more often, and treat the operating airline as the last word.
