PUT/v2/cart/{id}

Add passengers

Replace the passenger list. Ages are measured on the departure date, not today.

Bearer tokenAuthority: B2C_CART_UPDATEhttps://booking.aerolink.dev

Ownership is checked first. A cart that does not exist and a cart that belongs to someone else return the same 404, so ids cannot be probed. Passenger count and types must match what the cart was priced for. Note the 406 status on age-band failures — it is not 400.

Business rules

For Sabre carts, a C02–C11 type whose real age falls in a different band is re-bucketed before matching.
Passport numbers are checked against existing bookings on the same flight and date.
