IATA Standards Coverage Map
The single source of truth for what IATA-standardised messages the Aviation Hub supports today, what's on the published roadmap, and how each standard maps to the commercial fuel lifecycle. Written for a technical audience — no hedging, proper IATA designations throughout.

1. Why this matters
The aviation fuel industry uses IATA-standardised messages across two distinct domains. The commercial domain covers tendering, contracting, transactions, and settlement — the buyer-seller relationship. The operational domain covers the refuelling event itself — what happens at the aircraft on the ground, between the airline's operations and the into-plane agent.
These two domains use different standards families and different message timings. They serve different teams in an airline, different vendors on the supplier side, and different software systems on both sides.
The Aviation Hub sits on the commercial side. Our role is to make the buyer-seller relationship efficient by automating commercial-message exchange end-to-end — tender → ticket → invoice → settlement. We're extending coverage to include the commercial-relevant operational summary (AIDX Fuel Summary) because it closes the verification loop between the refuelling event and the commercial transaction. We don't duplicate operational-side platforms — we connect to them.
2. The standards families we work with
Three IATA standards families are relevant to commercial aviation fuel. The Hub processes messages from all three.
IATA Fuel XML (maintained by FDSG)
IATA IS-XML
Simplified Invoicing and Settlement, Industry Standard XML. The standardised invoice schema used by IATA's SIS platform — 2,500+ operators, 500+ non-airline members.
AIDX
Aviation Information Data Exchange. The IATA standard for operational flight data; the Fuel Summary addendum carries fuel-specific operational data.
| Message | Purpose | Status on the Hub |
|---|---|---|
| IATA Fuel XML Tender & Bid | Tender invitations, bid responses, awards, confirmations |  |
| IATA Fuel XML Transaction | Fuel tickets — the per-aircraft, per-refuelling delivery record | |
| IATA Fuel XML Invoice | Commercial fuel invoices, supplier to airline | |
| IATA Fuel XML Operational | Operational fuel data tied to the refuelling event — Fuel Summary specifically |  |
| IATA IS-XML Fuel Invoice | Invoice exchange via the SIS / IATA Clearing House settlement workflow | |
| AIDX Fuel Summary | Operational refuelling summary bridging airline-ops/IPA to the commercial flow | |
Scope note — the IATA Fuel XML Operational standard also defines preliminary, revised, and final fuel-order messages; the Hub implements the Fuel Summary message only. Order-orchestration stays with airline-ops/IPA systems.
3. The commercial fuel lifecycle, mapped to standards
The lifecycle has five stages. Each is dominated by one or two message types, each from a specific standard family.
| Stage | What happens | Standard | Hub today |
|---|---|---|---|
| Sourcing | Airline issues a tender; suppliers bid; airline awards | IATA Fuel XML Tender & Bid | |
| Contracting | Awards become contracts; pricing and credit lines set | IATA Fuel XML (awarded bid) | |
| Transaction | Into-plane agent issues a fuel ticket reflecting the refuelling event | IATA Fuel XML Transaction or AIDX Fuel Summary | |
| Settlement | Supplier issues invoice; airline approves; payment settles | IATA Fuel XML Invoice or IATA IS-XML | |
The Hub processes every stage of the commercial lifecycle today, with the AIDX-route and the SIS-route settlement variant next on the roadmap.
4. Coverage snapshot
LIVE TODAY3 standards in production
- Tender & Bid — full lifecycle, incl. rejection
- Transaction — ticket exchange, complaints
- Invoice — direct exchange, credit notes
All three IATA Fuel XML standards are in production on the Hub today
LIVE BY Q3 2026
3 items committed
- Fuel Summary — closes refuelling → invoice loop
- IS-XML Invoice — SIS settlement route
- AIDX Fuel Summary — operational verification
Confirmed by development — all three land on the Hub by end of Q3 2026.
OUTSIDE IATA SCOPE
Supported as Premium
- Price notifications, FX rates, market data
- Density data, flight schedules, flight ops
- Ad-hoc fuel requests, credit line status
Transformable from any format we accept — plus the eDoc custom-payload channel.
5. What this means for the Hub user
If you exchange any of the three live standards — Tender & Bid, Transaction, Invoice — you can use the Aviation Hub Basic tier today. Free, permanent, no setup fees.
If you also exchange non-IATA-standard fuel data — price notifications, FX feeds, ad-hoc requests, custom payloads — Premium handles the transformation and routing.
If you're waiting on SIS-route invoicing or the AIDX Fuel Summary bridge — these are roadmap items, committed live by end of Q3 2026. They'll join the Basic tier when delivered, addable to your existing Hub connection without re-integration.
If you're an airline that wants commercial fuel data verified — the Hub validates tickets against contracted pricing, conversion factors, and ticket history today, and against independent flight event data where available.
6. Standards governance
We participate in the standards we implement. Atraxo is an active contributor to the FDSG working groups and tracks SIS and AIDX evolution through IATA membership. When the standards change, our implementation follows.
No proprietary formats. Every message either follows a published IATA standard, or — for Premium-tier outside-scope messages — uses the partner's existing format unchanged.
No vendor lock-in. If you ever leave the Hub, your IATA XML investment moves with you intact.

8. Change log
This page is the live record of standards coverage. Updates land here whenever a roadmap item goes live, a new standard family is added, or an existing standard adds a new message type. Current as of 2026-08-19. All three roadmap items are committed for delivery by end of Q3 2026, confirmed by development.
Every message the Hub processes either follows a published IATA standard, or moves your existing format unchanged.
