Flight transaction state tek `status` alanıyla güvenli yönetilemez. Reprice, booking/order, payment, ticket/document ve schedule-change state'leri bağımsız lifecycle'lardır.

## State separation

```text
OfferState
OrderState
PaymentState
TicketState
ScheduleChangeState
ServicingState
```

Örneğin:
- Order CONFIRMED,
- Payment AUTHORIZED,
- Ticket PENDING

aynı anda geçerli olabilir.

## Reprice

Reprice sonucu:
- MATCHED,
- PRICE_CHANGED,
- UNAVAILABLE,
- EXPIRED.

PRICE_CHANGED kullanıcının tekrar onay vermesini gerektirebilir.

## Ticketing

Order/PNR oluşması ticket issued anlamına gelmez. Ticket/document number ve issuance status ayrı tutulmalıdır.

## Schedule change

Airline-initiated change:
- detected,
- pending action,
- accepted,
- alternate selected,
- refund/cancel

gibi ayrı lifecycle gerektirir.

## Unknown outcome

Order create veya ticket issue timeout'u:
- FAILED değil,
- UNKNOWN.

Retrieve/reconcile yapılmadan duplicate operation gönderilmemelidir.

## Reconciliation

Periodik job:
- local order,
- provider order/PNR,
- ticket/documents,
- airline changes

arasında drift kontrol etmelidir.

## Observability

- reprice change rate,
- order unknown rate,
- ticket pending age,
- schedule-change pending age,
- servicing failures,
- reconciliation drift.
