TKCONNECT represents Turkish Airlines' NDC/direct-distribution model across agency UI, aggregator and direct API paths. Model it around offer/order ownership and servicing capability, not as one generic airline-search endpoint.

Turkish Airlines offer/order lifecycle

Direct API and aggregator access can expose the same airline supply while differing in authentication, certification and servicing capability.

Canonical boundary

Keep itinerary, offer, fare family/brand, baggage, ancillary, provider offer reference, order/booking reference, ticket/document state and servicing capability separate.

Do not lose airline source identity during normalization.

Search → Offer → Order

text
SEARCH
 -> OFFER
 -> SELECT
 -> REVALIDATE if required
 -> ORDER/BOOK
 -> PAYMENT/TICKET
 -> RETRIEVE
 -> CHANGE/CANCEL/SERVICE

A search result is not a booking guarantee. Preserve offer expiry and fare conditions through the booking boundary.

Idempotency

A create timeout is not proven failure:

text
CREATING -> CONFIRMED
         -> REJECTED
         -> UNKNOWN -> retrieve/reconcile

Do not duplicate order creation while state is UNKNOWN.

Observability

Track search latency, offer count, offer expiry, revalidation-change rate, unknown-order age, ticketing success, servicing failures and reconciliation drift.

Production checklist

  • access/certification path verified
  • direct vs aggregator source explicit
  • offer/reference preserved
  • fare family + baggage normalized
  • UNKNOWN recovery implemented
  • servicing capability matrix available
  • ticket/document state separate from booking state
