Flight tracking
Know what changed before it costs you time
byAir watches your flight day for the changes that actually matter: delays, gates, terminals, boarding, cancellations, baggage and inbound aircraft context. You get clear alerts early enough to decide what to do next.

byAir turns flight changes into alerts you can act on.
Airline apps are useful, but not built around your decisions
Airline apps are built around the airline's operation: check-in, boarding flow, customer support and disruption management. Some airlines do not have a strong passenger app at all. And when a delay is still operationally uncertain, the airline may not be motivated to alert everyone early. byAir is built around the traveler: helping you understand what changed and what it means for your next move.
Airline appUseful for airline-controlled tasks
Good for check-in, boarding passes and booking support when the airline has a solid app. But update timing follows the airline's operation and communication policy.
byAirUseful for traveler decisions
byAir watches independent aviation signals so you can decide whether to leave, wait, walk to a new gate, warn someone meeting you or keep an eye on the aircraft coming in.
Why your alert can arrive earlier
Airport information rarely changes everywhere at once. A delay may show up in one signal before the airline app, a gate may appear in airport data before a push notification, and the aircraft operating your flight can reveal risk before boarding catches up.

From scattered updates to one useful alert
Flight days are full of small changes. byAir focuses on the changes that can affect your time, your gate, your connection or the people waiting for you.
01
Detect the change
byAir watches for meaningful movement in delays, gates, terminals, boarding, cancellations, baggage and the aircraft scheduled to operate your flight.
02
Read the context
A five-minute shift three hours before departure is not the same as a gate change during boarding. byAir weighs what changed, when it changed and what was known before.
03
Send the next step
The alert is written for the traveler: what changed, why it matters now and what you may need to watch next.
Spend less time guessing at the airport
Flight tracking should help you make better small decisions throughout the travel day, not just show another status 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.

Auto-Scan Email can find booking confirmations, import upcoming trips, and rebuild past flight history before byAir starts tracking every change.
More than a status screen
The useful part is not seeing every raw signal. It is knowing which change matters to you right now.
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
Good for looking up raw status. Less helpful when 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.
The proof behind the alerts
There is no single perfect flight-data source for every airline, airport and region. byAir compares five global providers and uses patterns learned from 7M+ tracked flights to decide which signal is most likely to be right in the current context.
7M+tracked flights informing byAir source reliability
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.
