Flight tracking
Flight tracking that knows which source to trust
byAir uses five global flight-data providers and experience from tracking 5M+ flights to decide which source is most reliable for each airline, airport and route.

Decision layerSource confidence: High
Five providers compared before the alert reaches you.
Airline apps are not neutral flight trackers
Airlines do not always rush to tell passengers about delays. Their priority is keeping boarding, gate staffing and passenger flow under control. If a delay is still operationally uncertain, the airline often has more incentive to keep passengers near the gate than to send an early alert. And not every airline has a useful passenger app in the first place.
Airline appBuilt around the airline operation
The airline controls one passenger flow, one booking channel and one communication policy. Many airlines do not have a strong app at all, and updates can arrive late while a disruption is still being managed internally.
byAirBuilt around the traveler
byAir watches independent aviation signals across providers, airlines and airports so you can react earlier to meaningful delay, gate, terminal and status changes.
Five providers. One clearer answer.
There is no single perfect flight-data source for every flight in the world. Each global provider is stronger or weaker with different airlines, airports, regions and update types. byAir combines five of them instead of trusting one feed blindly.

How byAir decides what to show
Raw aviation data often conflicts. byAir turns those signals into one traveler-facing answer by comparing source freshness, context and historical reliability.
01
Collect five signals
We monitor five trusted global providers instead of depending on one airline system or one generic tracker feed.
02
Compare confidence
Source quality differs by airline, airport, route, region and update type, so byAir weighs the context before trusting a change.
03
Notify when it matters
You get clear alerts for delays, gate changes, terminal updates, boarding, cancellations, baggage and inbound aircraft context.
What you get as a traveler
Flight tracking should reduce airport uncertainty. byAir keeps the important changes visible on your phone, watch and lock screen.
Delay alerts
Know when departure or arrival time changes before you lose time at the airport.
Gate and terminal changes
See gate, terminal and baggage updates where the airport and provider data supports them.
Inbound aircraft
Understand whether the aircraft operating your flight is late before boarding is announced.
Flight status
Follow scheduled, boarding, en route, landed, cancelled and other status changes in one place.
Live surfaces
Use iOS Live Activities, Android Live Updates, widgets and push alerts during the flight day.
Smartwatch support
Check key flight updates from Apple Watch and Wear OS without pulling out your phone.
Family updates
Keep people waiting for you informed without manually forwarding every airport update.
Trip timeline
Keep flights, gates, baggage, documents and airport context organized around your trip.
Different from airline apps and generic trackers
The difference is not just more data. It is how byAir interprets conflicting data for the person actually traveling.
Airline apps
Useful for check-in and airline-controlled actions when the airline has a good app, but communication timing follows the airline operation and only covers that airline.
Generic trackers
Often show raw status from one or a few feeds. That can be enough until sources disagree, a provider is weak for your route, or the alert needs traveler context.
byAir
Combines five providers with learned reliability from millions of tracked flights, then writes traveler-focused alerts from the current context in 20 languages.
Built from millions of tracked flights
Tracking millions of flights gives byAir practical knowledge about how aviation data behaves: which airports publish gates early, which airlines lag on delay updates, where provider conflicts are common, and which source usually proves right.

Route-level patterns
byAir learns how timing and provider quality behave across repeated routes and connections.
Airport behavior
Some airports publish gates, terminals and operational changes earlier or more consistently than others.
Conflict resolution
When sources disagree, byAir can prefer the signal that has historically been more reliable in that context.
Common questions
What flight-data sources does byAir use?
byAir compares five global flight-data providers. Each provider can be stronger or weaker for different airlines, airports, regions, routes and update types, so byAir does not rely on a single feed for every flight.
Why can byAir alert me before the airline app?
Airline apps follow the airline's own communication flow, and some airlines do not have a strong passenger app at all. byAir watches independent aviation signals too, so meaningful delay, gate, terminal or inbound-aircraft changes can often appear earlier.
Why does flight status differ between byAir, the airline app and the airport screen?
These systems can update from different sources at different times. byAir compares provider feeds and uses learned reliability from millions of tracked flights to choose the signal that fits the current flight context.
Does byAir track gate, terminal and baggage changes?
Yes, when those details are available from our providers. Gate, terminal and baggage coverage depends on the airport, airline, region and how quickly the operating system publishes changes.
Does byAir track inbound aircraft and delay risk?
Yes. Inbound aircraft context can help you understand delay risk before boarding information or a new gate time is officially announced.
How does byAir decide what notification text to send?
byAir does not just forward a raw status change. Its notification system considers the current flight context, what changed and what the traveler needs to understand next, with localized alert text available in 20 languages.
Is byAir a live flight radar like Flightradar24?
byAir is focused on traveler-facing flight status rather than only aircraft position. It combines status, delay, gate, terminal, baggage, inbound aircraft and notification context so you can make better decisions around the trip.
Is flight tracking free in byAir?
byAir has a free plan for basic current and future flight tracking. Pro unlocks more real-time updates and advanced alerts such as delay predictions, full notifications and smartwatch surfaces.
