The critical question in agentic travel is not "what can the agent do?" but **what side effect did the user authorize, under which limits?**

## Authorization layers

Separate user intent, selection approval, purchase mandate, payment authorization, booking authorization and servicing authorization.

## Mandate model

A mandate should carry subject, operation scope, product/offer scope, amount/currency limits, merchant/provider scope, validity window, one-time/reusable semantics, allowed servicing actions, revocation state and evidence reference.

## Delegated payment

Delegated payment is not unlimited spending authority. Bound it by amount, currency, destination/provider, refundability constraints, time window, transaction count and ancillary permissions.

## Human-in-the-loop checkpoints

Useful checkpoints include price changes, non-refundable products, unexpected penalties, delegated-limit breaches, new payment methods, passenger/document changes, replacement booking while the first remains UNKNOWN and financially meaningful servicing.

## Confirmation evidence

Persist immutable evidence tied to purchase intent and offer version rather than a generic "user said yes" flag.

## Expiry and revocation

Mandates can expire, be revoked, become invalid after offer changes, or require new confirmation when thresholds are exceeded.

## Failure modes

Using stale mandates for new offers, exceeding cumulative delegated limits, reducing confirmation evidence to logs, treating servicing as covered by purchase authorization and using revoked authorization from cache.

## Observability

Track mandate issue/revocation, HITL trigger rate, confirmation acceptance/rejection, prevented limit breaches, expired authorization attempts and mandate-to-transaction correlation.

## Production checklist

Use explicit mandate schemas, operation scope, amount/currency limits, expiration/revocation, immutable evidence, HITL policy, reprice invalidation, separate servicing authorization and complete audit trails.
