Check refund eligibility, commit a refund, or check refund status for a booked flight. No login required — authenticate with the Jinko booking reference and traveler last name.

PREREQUISITES:
- booking_ref (JNK-XXXXXX format) and last_name of the primary traveler from the booking confirmation email.

WORKFLOW:
1. action="check" with booking_ref + last_name → review eligibility, amounts, penalties
2. If refundable and user confirms, action="commit" with booking_ref + last_name → capture refund_reference
3. action="status" with booking_ref + last_name (+ optional refund_reference) → poll progress

IMPORTANT:
- Always check eligibility before committing.
- Always get explicit user confirmation before committing a refund.
- Some refunds require manual processing — the response flags support_level and is_automatable.
- Refund amounts may include penalties.

Examples

Check refund eligibility (authenticated path): 
{
  "name": "flight_refund",
  "arguments": {
    "action": "check",
    "order_id": "TF-ORDER-123"
  }
}
Check refund eligibility (guest path): 
{
  "name": "flight_refund",
  "arguments": {
    "action": "check",
    "booking_ref": "JNK-ABC123",
    "last_name": "Doe"
  }
}
Commit a refund after checking eligibility: 
{
  "name": "flight_refund",
  "arguments": {
    "action": "commit",
    "booking_ref": "JNK-ABC123",
    "last_name": "Doe"
  }
}
Response includes a refund_reference. Poll refund_status until terminal: 
{
  "name": "flight_refund",
  "arguments": {
    "action": "status",
    "booking_ref": "JNK-ABC123",
    "last_name": "Doe",
    "refund_reference": "REF-xyz789"
