Overview

Retrieve an existing flight checkout session (prebook) by ID, including any ancillary services already attached and a live catalog of remaining attachable services.

When to Use

• Resume checkout — Reload prebook state after the user navigates away
• Confirm attached ancillaries — Show selected seats/bags before final book
• Reuse payment intent — Returns the stored Stripe transactionId / secretKey as-is (GET does not create or refresh a PaymentIntent)
• Credit balance — Optionally include a live credit-line snapshot with includeCreditBalance=true

What You Get

• Same core FlightPrebookData shape as POST /flights/prebooks / attach-services (journey, pricing, payment intent fields, servicesAttachable)
• booking.selectedServices / booking.bookedServices when services were attached
• Live servicesAttachable from the provider (not persisted)
• Existing payment fields conserved from create/attach
• Optional creditLine when includeCreditBalance=true (live remaining credit when the account can cover the prebook price)

Quick Start

Provide the prebookId returned from POST /flights/prebooks in the URL path. Optionally pass includeCreditBalance=true to include credit-line availability.
