Flight updates conflict. See the evidence.

The airline, the airport and the aircraft each tell a different story about the same flight. We listen to all three and hand you one answer with a confidence score.

AIRLINE

Airline systems

Airline schedules and operational messages provide flight updates. Coverage and field availability vary by carrier and data source.

AIRPORT

Airport & ground

Airport operational databases for gates, terminals, stands and baggage belts: the ground truth the airline feed often learns last.

Gate + belt level
AIR

Airborne positions

ADS-B and radar-derived positions confirm what actually happened: real off-block, real wheels-up, and diversions caught mid-flight.

MODEL

The confidence model

When sources conflict, each field resolves to a winning value with a score and full attribution. You choose the threshold at which your app speaks up.

Per-field confidence
How it works

Subscribe once. We push.

Subscribe with a carrier, flight number and date; one call returns the current state and registers your webhook. From then on we push: schedule change, delay, gate, terminal, baggage belt, diversion, cancellation, each as a typed event with old value, new value and confidence attached, within seconds of any source changing. The flight does not need to be booked through OnArrival.

In depth

From polling to push.

Receive flight changes through webhooks with timestamps, source details and confidence scores. Your app decides when to notify the traveller.

01

One event schema, every source

Airline systems, airport operational databases and airborne positional data emit wildly different messages. They arrive at your webhook as one typed event: what changed, old value, new value, when, and how sure we are.

Normalise
02

The confidence model

Sources disagree constantly: the airline says on time, the airport says the stand is empty, the transponder says the aircraft never left the origin. Each field carries the winning value with a confidence score and full source attribution, so you decide when to notify.

Resolve
03

Gate, terminal, baggage belt

The changes that actually ruin a travel day rarely reach the airline app in time. Gate and terminal moves and belt assignments push as first-class events, down to the last belt change after landing.

Ground
04

Diversions, detected in the air

Position data can help detect a diversion before a schedule feed updates. Show the source, timestamp and confidence alongside the revised destination and arrival estimate.

Airborne
05

Historical on-time performance

5 years of punctuality per route, carrier and flight number: delay distributions, cancellation rates, seasonal patterns. Set expectations at booking time, or price risk with it the way our Travel Fintech underwriting does.

Standalone by design

Who it's for

Who uses Flight Status?

OTA & TMC

Travel sellers

Use delay, gate and cancellation updates for traveller notifications and rebooking workflows. Source timestamps and confidence help decide when to send an alert.

EXAMPLE WORKFLOWNotify a traveller about a confirmed gate change.
Fintech & super-apps

Cards & apps

You see the ticket purchase on the card. Subscribe to the flight behind it and your app becomes the travel companion, without selling a single ticket.

EXAMPLE WORKFLOWTrack a flight booked outside OnArrival.
Insurer

Parametric products

Delay and cancellation events with confidence and timestamps are the trigger feed for parametric payouts, the same feed our own Travel Fintech products settle on.

Questions

Flight Status: common questions

Something we haven’t covered? Talk to the team. We can help you work through your integration.

Do I need to book flights through OnArrival to use Flight Status?

No. Flight Status is a standalone service. Subscribe to any scheduled commercial flight by carrier, number and date, whether it was booked on your platform, through OnArrival, or anywhere else. Bookings made through our Flights API can auto-subscribe if you want them to.

Airlines, airports and trackers disagree. Whose number do I show?

Ours, with a score. Every field resolves to a winning value through the confidence model, with the raw sources and their timestamps attached. Set a threshold and only notify travellers above it; below it, hold back or show a range.

How fast do events actually arrive?

Median under 5 seconds from a change appearing in any source to your webhook receiving the typed event. Delivery is signed, retried with backoff, and replayable if your endpoint was down.

Which events are covered?

Schedule changes, delay and revised-estimate updates, gate, terminal and baggage-belt changes, diversions and cancellations, plus actual off-block, take-off, landing and on-block times. Each event carries the old value, the new value, confidence and source attribution.

Can I poll instead of using webhooks?

Yes. Every subscribed flight exposes a current-state endpoint that answers from our store, not from a live upstream call, so reads are fast and never rate-limited by an airline. Most integrations still poll only as a reconciliation sweep; push is the point.

How far back does the historical on-time data go?

5 years of punctuality per route, carrier and flight number: delay distributions, cancellation rates and seasonal patterns. Use it to set expectations at booking time or to price risk, the way our Travel Fintech underwriting does.

What to monitor after a travel booking is confirmed

Search latency cannot tell you whether a flight changed or a refund arrived. Post-booking monitoring needs to detect supplier changes, missing updates and delays in telling the traveller.

Post-booking service: who handles changes and refunds?

A confirmed booking still needs support when a flight changes, a traveller cancels or a refund is delayed. Customers need a clear status, a next step and someone responsible for the outcome.
