Korean Air (LHR) Flight API

You need a reliable way to build Korean Air (KE) arrivals and departures for London Heathrow (LHR) into your app. By the end of this guide, you’ll query schedules for KE, filter for LHR, interpret key fields (status, times, terminals, gates, codeshares), and choose the right FlightLabs endpoints for live tracking, planning, and analysis—while handling time zones, polling, and caching safely.

About Korean Air (KE) and the LHR context

Korean Air (IATA: KE) is South Korea’s flag carrier. Its primary hub is Incheon International Airport near Seoul. Many KE long-haul services operate to and from London Heathrow (IATA: LHR), making LHR schedules and status a common requirement for travel apps, airport displays, and operations tools.

Which FlightLabs endpoints to use for KE at LHR

FlightLabs provides multiple endpoints relevant to KE and LHR. For schedules specifically, use the schedules endpoint. For live flight positions and status, use the real-time flight tracking feature. For planning and analytics, layer in future flights, historical flights, routes, and delay predictions.

You can explore the platform at www.goflightlabs.com and manage API access via MCP. To start building, create your key using Register.

Query KE schedules and filter for LHR

Schedules are the foundation for any KE–LHR experience. Use the schedules endpoint, then client-side filter by the LHR airport code in the arrival or departure section. The documented query pattern is:

• GET https://api.goflightlabs.com/flights-schedules
• Parameters: iataCode, type

For Korean Air arrivals into LHR, query KE schedules and filter records where arrival.airport == "LHR". For KE departures from LHR, filter where departure.airport == "LHR".

cURL: KE arrival schedules, then filter to LHR in your app

curl -G "https://api.goflightlabs.com/flights-schedules" \
--data-urlencode "iataCode=KE" \
--data-urlencode "type=arrival" \
--data-urlencode "api_key=YOUR_API_KEY"

Notes:

• Timestamps are ISO 8601 (e.g., 2024-03-20T08:00:00Z), which are UTC. Convert to Europe/London for LHR displays when needed.
• Filter results on the client by arrival.airport == "LHR" to isolate KE arrivals at Heathrow.

JavaScript example: fetch KE schedules and subset for LHR

async function fetchKoreanAirArrivalsAtLHR() {
const url = new URL("https://api.goflightlabs.com/flights-schedules");
url.searchParams.set("iataCode", "KE");
url.searchParams.set("type", "arrival");
url.searchParams.set("api_key", "YOUR_API_KEY");

const res = await fetch(url.toString(), { method: "GET" });
if (!res.ok) throw new Error(`HTTP ${res.status}`);
const payload = await res.json();

// Expected structure aligns with the schedules sample shown below:
// payload.success (boolean), payload.data.schedules (array)
const schedules = (payload && payload.data && payload.data.schedules) || [];

// Filter for LHR arrivals
const lhrArrivals = schedules.filter(item => {
// item.arrival.airport is the IATA code in the sample
return item.arrival && item.arrival.airport === "LHR";
});

// Map essential display fields
return lhrArrivals.map(item => ({
flightNumber: item.flight_number,
airline: item.airline && item.airline.iata,
scheduledUTC: item.arrival && item.arrival.scheduled,
terminal: item.arrival && item.arrival.terminal,
// optional: gates or codeshares may appear depending on data availability
origin: item.departure && item.departure.airport
}));
}

fetchKoreanAirArrivalsAtLHR()
.then(list => console.log("KE arrivals at LHR:", list))
.catch(err => console.error(err));

If you need a broader future view (e.g., for planning weeks ahead) or a live board with en-route positions, combine schedules with Future Flights and Real-time endpoints, respectively.

Official sample responses and how to interpret fields

Below are official samples to illustrate key fields you’ll parse for displays and monitoring. These samples are verbatim, including the values shown.

Real-time Flight Tracking: sample

{
"success": true,
"data": {
"flight": {
"iata": "AA123",
"icao": "AAL123",
"number": "123",
"status": "en-route",
"departure": {
"airport": "JFK",
"scheduled": "2024-03-20T10:00:00Z",
"actual": "2024-03-20T10:05:00Z",
"terminal": "8",
"gate": "B12"
},
"arrival": {
"airport": "LAX",
"scheduled": "2024-03-20T13:15:00Z",
"estimated": "2024-03-20T13:20:00Z",
"terminal": "4",
"gate": "45A"
},
"position": {
"latitude": 39.8729,
"longitude": -98.7372,
"altitude": 35000,
"speed": 495,
"heading": 270
}
}
}
}

What to use:

• flight.status: Use for en-route, landed, cancelled, delayed, etc.
• departure.scheduled, departure.actual: Calculate departure delay (actual - scheduled).
• arrival.scheduled, arrival.estimated: Show scheduled vs updated ETA; compute arrival delay.
• departure.terminal/gate and arrival.terminal/gate: Populate terminal/gate boards.
• position: For live maps and en-route visuals (latitude, longitude, altitude, speed, heading).

Apply the same logic to KE flights. For instance, KE “en-route” to LHR will reflect in status and position, while terminal and gate fields drive your LHR display cards.

Flight Schedule: sample

{
"success": true,
"data": {
"schedules": [
{
"flight_number": "UA456",
"departure": {
"airport": "SFO",
"scheduled": "2024-03-20T08:00:00Z",
"terminal": "3"
},
"arrival": {
"airport": "ORD",
"scheduled": "2024-03-20T14:15:00Z",
"terminal": "1"
},
"aircraft": {
"type": "Boeing 787-9",
"registration": "N123UA"
},
"airline": {
"name": "United Airlines",
"iata": "UA"
}
}
]
}
}

What to use:

• flight_number and airline.iata: Present KE flight designators and support comparisons with codeshares.
• departure.scheduled and arrival.scheduled: The backbone of your timetables; these are UTC (Z).
• departure.terminal and arrival.terminal: Useful for LHR terminal boards.
• aircraft fields: For aircraft-type visuals or operational context.

Three KE–LHR use cases built on FlightLabs

1) KE flight status pages for LHR (live tracking + schedules)

• Start with schedules (iataCode=KE) and filter for LHR to list expected flights for the day.
• For each flight, enhance with real-time status and estimated times. Use status, departure.actual, arrival.estimated, and gate/terminal fields to show up-to-the-minute context.
• Time zones: Display both local (Europe/London) and UTC. When converting from “Z” timestamps, account for daylight saving time in London.
• Polling/caching: Poll real-time data every 30–90 seconds per flight. Cache for 15–30 seconds to avoid flicker and API overuse. For schedules, cache per day or per hour depending on your refresh UX.

2) Delay monitoring and alerts for KE at LHR

• Use schedules for the plan of record. Augment with real-time to detect deviation: delay = (actual - scheduled) for departure and (estimated - scheduled) for arrival.
• Trigger alerts when deviation crosses your thresholds (e.g., 15 minutes). Use terminals and gates for operational notifications to ground teams.
• Optionally, consult delay-related features at Flight Delay to anticipate risk before departures.

3) Route and capacity planning for KE’s LHR service

• Pull KE routes via Routes to understand available city pairs that include LHR.
• Combine with Future Flights to view forward flight plans and project loads.
• Enhance dashboards: group by route (e.g., ICN–LHR) and overlay scheduled times for crew and gate planning.

Practical implementation details (save an hour)

• Time zones: API schedule and real-time timestamps are in UTC (suffix Z). Convert to local time zones only for display. Store and compare in UTC to avoid DST confusion.
• Polling cadence: For live pages, 30–90 seconds per flight is a reasonable polling interval. For airport-wide boards, stagger calls across flights and cache each response briefly.
• Caching: Consider a layered approach—daily schedule cache (minutes to hours), per-flight real-time cache (15–30 seconds), and derived fields cache (e.g., computed delays) synchronized with real-time refreshes.
• Cancelled or diverted: Treat flight.status values like “cancelled” or “diverted” as terminal states; suppress ETA/position in UI and provide a clear label with any available terminal/gate info.
• Pagination for schedules: If you receive large result sets for iataCode=KE, implement pagination or windowing by date/time on the client side. If the API returns pagination metadata, honor it; otherwise, chunk by date.
• Codeshares: Show the operating carrier’s flight number prominently. When multiple airline codes reference the same physical flight, group them in the UI and map them to one real-time object to avoid duplicates.
• Airports and terminals: Terminal values are strings and may be null/empty; handle missing gates and terminals gracefully.
• Geospatial units: position.altitude is typically in feet; speed in knots; heading in degrees. Show a concise label or convert to user-preferred units.
• Error handling: Implement retries with backoff for transient network errors. On API error payloads, surface a minimal “data temporarily unavailable” message to end users.

Objective comparison of endpoints for KE–LHR workflows

When your goal is a KE–LHR experience, different endpoints shine in distinct roles. Below is a neutral comparison focused on developer ergonomics and typical LHR requirements.

Across all of these, the JSON structure stays consistent and predictable for developers. Reference field names and examples are available in the Documentation.

End-to-end flow for KE arrivals at LHR

1) Query schedules by airline

Use iataCode=KE with type=arrival to retrieve KE arrival schedules. Cache the list for the remainder of the operational window (e.g., a few minutes during heavy refresh cycles, or an hour for static views).

2) Filter for LHR

Client-side filter where arrival.airport === "LHR". Pre-calculate local-time fields (Europe/London) and label each row with UTC to minimize confusion.

3) Overlay real-time status

For flights within a configurable “active window” (e.g., departing within ±6 hours, currently en-route, or arriving soon), fetch live flight status and position. Compute and display delays and update gates/terminals as they change.

4) Handle exceptional states

When status is cancelled or diverted, pin a badge along with any available terminal/gate information and suppress irrelevant ETAs. Keep the record on the board in a “final” state for a grace period to avoid data flicker.

5) Logging and observability

Log each API call’s latency and response size. If your traffic is high, pace the calls and leverage short-term caches. Use MCP to monitor usage and keys across environments.

Authentication, pricing, and getting started

FlightLabs uses an API key for authentication. Add your key as an api_key parameter in your requests. You can obtain a key via the Register page.

FAQ

How do I get only Korean Air arrivals for LHR?
Query schedules with iataCode=KE and type=arrival, then filter records where arrival.airport equals "LHR".

How should I handle time zones for LHR displays?
Times are returned in UTC (Z). Store and compare in UTC; convert to Europe/London for display. Show both when helpful.

What polling rate is appropriate for live KE flights?
A 30–90 second interval per active flight is common. Cache the per-flight result for 15–30 seconds to smooth updates and reduce load.

How do I detect cancellations or diversions?
Check flight.status. When cancelled or diverted, update your UI badge and avoid showing stale ETAs or positions for the original route.

Is there pagination for schedules?
If large result sets occur, implement pagination or client-side windowing by time range. If pagination metadata is returned, adhere to it; otherwise, chunk by date/time.
