OTAIP — Open Travel AI Platform

75 AI agents. 6 supplier adapters. 2,985 tests. One platform for the entire travel distribution stack.

OTAIP is an open-source AI agent orchestration platform purpose-built for the travel industry. It covers the full lifecycle — search, price, book, ticket, change, refund, settle — across GDS, NDC, and Offers & Orders distribution channels.

What You Can Build on OTAIP

End-user products

• A full-service OTA — search across multiple suppliers in parallel, evaluate offers against traveler context, book, take payment, issue tickets, retrieve bookings, void, cancel, exchange, refund. Multi-channel fallback (NDC → GDS → direct) when the primary supplier fails.
• A complete TMC — everything an OTA does, plus traveler profiles with loyalty, SSRs, and document storage; corporate account policies (cabin ceilings, fare limits, advance-purchase thresholds, blocked carriers, negotiated fares); mid-office automation (pre-ticketing validation, queue management); duty of care (locate travelers by airport and time, 20-country destination risk data); corporate reporting; BSP and ARC reconciliation.
• An airline distribution platform — NDC Offers & Orders retailing (AIDM 24.1 OrderCreate / OrderRetrieve / OrderChange / OrderCancel) coexisting with GDS PNR via BookingReference. Offer construction with fare rules, taxes, and ancillaries. Ticketing with ETR plus EMD-A and EMD-S. Hooks for dynamic pricing and revenue management.
• A hotel booking platform — HAIP adapter, property deduplication (Jaro-Winkler + Levenshtein + Haversine), content normalization (room taxonomy, 11 amenity categories), rate comparison with parity detection, California 24-hour cancellation rule, CRS-to-PMS confirmation verification, virtual card payment routing.
• A travel AI assistant — AgentLoop plus pipeline validator with six gates that prevent LLM hallucinations (no fabricated offer IDs, no destination drift mid-flow, no ticketing without approval). Auto-generated Claude MCP tool definitions, OpenAI function-calling schemas, and standalone JSON Schema catalogs, all derived from AgentContract.

Operational platforms

• A BSP/ARC reconciliation system — HOT file parser (EDI X12 plus fixed-width ASCII), IAR parser (X12 / CSV / XML), agency-to-BSP matching with discrepancy detection, commission management (overrides, tiers, effective dates, net remit), ADM dispute tracking with 15-day windows and 5-day warnings, ACM processing.
• A revenue accounting system — coupon lift (OPEN → USED), deferred revenue calculation, interline settlement (SIS proration), multi-dimensional financial reporting (9 report types), decimal-safe currency arithmetic via decimal.js.
• An IRROPS response engine — 60-minute delay trigger, EU261 compensation calculation (distance bands, 31 countries, 50-percent reduction windows), US DOT 220% / 400% denied-boarding rules, alliance and interline reprotection, waitlist management.
• A compliance and audit platform — EventStore with full audit trail, PII redaction, 2555-day retention (IATA / PCI), 1095-day GDPR retention, right-to-erasure, per-event aggregation with p50 / p95 / p99 percentiles.
• A governance dashboard — performance audit (latency percentiles, error rates, degraded-agent detection with configurable thresholds), routing audit (per-channel success rates, fallback frequency), deterministic recommendation engine, alert agent with separate GDS and NDC thresholds.

Specialized components

• A fare intelligence engine — ATPCO Categories 1–20 parsing, branded-fare shopping, fare construction (NUC × ROE, TPM/MPM proration, HIP/BHC/CTM checks), OfferEvaluatorAgent with multi-dimensional scoring against traveler profiles (business time-critical, leisure, price-sensitive).
• An ancillary merchandising platform — baggage, seats, meals, lounge access, insurance, per-passenger and per-segment pricing, RFIC A–I classification, EMD-A and EMD-S issuance.
• A corporate policy enforcement engine — cabin ceilings, advance-purchase thresholds, fare limits, blocked and preferred carriers, bypass workflows, negotiated-fare enforcement.
• A document verification pipeline — passport regex per nationality, 6-month validity windows, APIS requirements by country, visa rules for 20+ destinations, pre-check-in readiness scoring.
• A loyalty accrual calculator — class and status multipliers, OneWorld / SkyTeam / Star Alliance partner tables, mile conversion.
• A multi-supplier search aggregator — parallel queries across GDS + NDC + LCC + aggregator adapters, source attribution per offer, per-adapter timeouts with partial-result handling, circuit-breaker-aware channel selection.

Infrastructure to extend

• A plugin system — register third-party agents at runtime via PluginManagerAgent, semver validation, capability discovery.
• A CLI for operations — list agents by stage, dry-run pipeline validation against any contracted agent, list adapters with health status, search / price / book from the terminal.
• A reference OTA to fork — Fastify server, plain HTML/JS frontend, Duffel-or-mock adapter selection, multi-adapter search mode, complete booking-to-ticket flow in examples/ota/.

Everything above is built from the same set of 75 typed agents and 6 supplier adapters — pick the ones you need, ignore the rest.
