Flight booking API and engine: every airline channel, one search
GDS, NDC and low-cost carrier content returned in one normalised result set, with fare families, seat maps and ancillaries where the airline provides them, your negotiated fares from Nexus beside public fares, and ticketing, changes and refunds through the same order model.
Three airline channels, three different worlds
GDS EDIFACT, airline NDC and LCC web APIs each have their own structures, fare logic, ticketing rules and servicing flows. Selling all three well usually means three integrations, three sets of edge cases and agents who know which screen to use for which airline.
One schema, one order, every channel
Synapse normalises every airline source into one offer and order model. Agents and travellers see one result set with the source marked, negotiated fares flagged as yours, and one flow for booking, ticketing, changes and refunds whichever channel the fare came from.
What a flight booking API should give you
A flight booking API is only as useful as the flows behind it. Search is the easy part. What decides whether a team can sell flights at scale is everything after: re-pricing before payment, holds and time limits, ticketing, seats and bags, changes, refunds and schedule changes. Elkanio’s flight booking API covers that full lifecycle in one order model, so a developer integrates once and your desk services every ticket the same way:
- Search across GDS, NDC and LCC sources in one request, deduplicated, with source and fare family on every result.
- Price and validate the chosen itinerary before payment, so price changes surface before the customer pays.
- Book, hold and ticket with time limits tracked per booking.
- Extras (seats, bags, meals) before and after booking, where the airline supports them.
- Service reissues, cancellations, refunds and voids through the same API.
Developers get it through Synapse; agents and sub-agents get the same flows inside Nucleus. For a buyer’s checklist, read the travel API evaluation checklist.
Flight API for India: GDS, NDC, LCC and aggregators together
Indian agencies rarely sell from one source. A typical stack combines a GDS (Amadeus, Sabre or Travelport), direct low-cost carriers such as IndiGo, SpiceJet, AirAsia, flydubai and Akasa Air, aggregators such as TBO, TripJack and Mystifly, and NDC for airlines whose best fares now live there (Verteil, Sabre NDC). Elkanio connects these through one schema and lets you set preference per airline or route. Your own series and negotiated fares join from Nexus. The connected suppliers are listed further down this page.
Booking engine, API or both?
Some teams want a ready flight booking engine for their desk and network; others want an API for their own app. Most need both. The same flights stack powers the agent desk in Nucleus, B2C sites on Nova, corporate booking in Orbit and direct API access. See B2B travel portal vs booking engine vs travel API.
Flights on the platform.
One result set across GDS, NDC and LCC
Public fares from every connected channel in one search, deduplicated and sortable, with the source shown and the same filters whatever the airline.
Fare families, seats and ancillaries
Branded fares, seat maps, bags, meals and other ancillaries where the airline provides them, priced from the airline and sold in the same basket.
Negotiated and private fares from Nexus
Consolidator, corporate and series fares loaded in Nexus appear beside public fares with their rules, commission and validity, marked as yours.
Ticketing, orders and PNRs
Instant or queued ticketing, hold and time-limit handling, order and PNR records stored with the booking and visible to finance in Vector.
Changes, cancellations and refunds
Voluntary changes, cancellations, refunds and reissues through the same API, with involuntary schedule changes surfaced to your team and travellers via Pulse.
Supplier routing and caching
Per-route routing by latency and success rate, cached availability refreshed so prices hold, and agentic healing when an airline changes its schema.
24 suppliers, one integration.
Connected through Synapse and normalised into one schema. Enable them per market in your configuration. Your own contracts and fares join through Nexus.

Questions about flights.
Do we need our own GDS or airline contracts?
Your existing contracts and credentials continue to work and are connected through Synapse. Where Elkanio holds airline NDC or aggregator connections, they can be enabled per market alongside yours.
Can agents see which channel a fare came from?
Yes. Every result carries its source (GDS, NDC, LCC or your negotiated fare) and the same result can be filtered or sorted by it, while booking and servicing stay identical.
How are changes and refunds handled across channels?
Through one order model. Voluntary changes, cancellations, refunds and reissues use the same API whichever channel issued the ticket, and involuntary schedule changes are surfaced to your team and travellers through Pulse.
Do you offer a flight booking API for OTAs and travel apps?
Yes. Synapse exposes search, price, book, ticket and servicing for flights in one REST schema, with a sandbox for your developers.
Which airlines and suppliers can I connect?
GDS (Amadeus, Sabre, Travelport), NDC (Verteil, Sabre NDC), direct low-cost carriers including IndiGo, SpiceJet, AirAsia, flydubai and Akasa Air, and aggregators including TBO, TripJack and Mystifly. Availability depends on your market and accounts; the connected suppliers are listed on this page.
Can I sell my own negotiated and series fares through the API?
Yes. Fares loaded in Nexus return beside public fares with their rules, marked as yours.
Is there a flight booking engine for sub-agents too?
Yes. Nucleus gives your network the same flights with your markups and credit rules.
