IATA's 2026 modularity POC sold lounge and eSIM inside ONE Order: what builders should take from it

IATA’s Airline Retailing Consortium asked IT providers to prove that modern retailing works across several vendors at once. TPConnects says its Astra Nova platform was named a winning solution in the 2026 Multi-Vendor Modularity Proofs of Concept, out of 13 teams that built live demos (TPConnects on LinkedIn).

Most coverage will focus on interline orders and settlement. For people building AI travel agents and OTAs, the part worth reading is how the demo treated the trip after the ticket.

What the demo did with ancillaries

Per TPConnects’ write-up, the partners were ATPCO, Lufthansa Systems, Ancileo, Neoke, FlyNava, M2P, IATA IFG, and Innovation Ink. The flow covered:

• At booking: a bundle with meals, Wi-Fi, insurance, cabin and checked bags, with flights, ancillaries, and third-party services such as insurance handled as independent products in one catalogue.
• After booking: extra baggage and seat selection added as a live purchase that modified the order in place, with no reissue.
• At the airport: lounge access and an eSIM bought as additional ancillaries through Innovation Ink’s Aura.
• Throughout: delivered-item status updates tracked in real time across check-in, boarding, and takeoff.

The pitch is one order that survives the whole journey, including disruption, without separate PNRs or EMDs.

Three takeaways for builders

1. Lounge and eSIM are being treated as order items, not affiliate links. In the demo they sit in the same order as the seat and the bag. That matches what travellers ask an agent for at the connection: a lounge at the next terminal, data on landing.

2. Delivery status matters as much as the sale. The demo tracks whether each item was actually delivered. An agent that books a lounge or an eSIM should store the supplier reference and be able to answer “did it go through?” later, not just return a confirmation once.

3. Standards are coming, but builders ship now. ONE Order adoption is an airline-side programme. If you are an OTA or an AI agent today, you can already quote and book these extras through supplier APIs and attach them to your own trip record. Our lounge API guide and eSIM API guide cover the tool shapes, and After Duffel covers how this sits next to a flights API.

How Ancilair fits

Ancilair exposes the non-ticket shelf as tools: anc.lounge.search then anc.lounge.book, eSIM plans, insurance quote then bind, fast track, and transfers, over MCP, REST, or CLI with one token. Prices are quoted on the call at the supplier’s rate with 0% markup, and paid steps run only after an explicit yes with an idempotency key. See lounges and eSIM.

What to watch

TPConnects says it will show the demonstration at the IATA World Passenger Symposium in Macao, which IATA lists for 28–29 October 2026 (IATA). Watch for which non-air ancillaries other winning teams included and how delivery status is exposed to sellers.
