# Additional baggage

> Retrieve and book additional baggage for an offer.

# Additional baggage

You add baggage after selecting a flight offer. Baggage options are specific to an offer, passenger, and flight segment.

## Retrieve baggage options

Request the latest offer with baggage options:

```http theme={null}
GET /v1/air/offers/{offerId}?include_additional_baggage=true
```

The response contains `additionalBaggageOptions`. Each option provides its price, maximum quantity, eligible passengers, and eligible segments.

```json theme={null}
{
  "additionalBaggageOptions": [
    {
      "optionId": "bag_option_...",
      "maximumQuantity": 2,
      "passengerIds": ["psg_1"],
      "segmentIds": ["seg_1"],
      "unitPrice": {
        "amount": "25.00",
        "amountCents": 2500,
        "currency": "USD"
      }
    }
  ]
}
```

<Note>
  Not every offer supports additional baggage. An empty array means no baggage options are currently available.
</Note>

## Select more than one bag

Use `quantity` to request multiple bags from one option. The quantity cannot exceed `maximumQuantity`.

```json theme={null}
{
  "additionalBaggage": [
    {
      "optionId": "bag_option_...",
      "quantity": 2
    }
  ]
}
```

You can also select different options for different passengers or segments.

```json theme={null}
{
  "additionalBaggage": [
    {
      "optionId": "bag_option_for_passenger_1",
      "quantity": 2
    },
    {
      "optionId": "bag_option_for_passenger_2",
      "quantity": 1
    }
  ]
}
```

## Create the order

Pass `additionalBaggage` to `POST /v1/air/orders` with the selected offer and passenger details.

The order total, wallet debit, payment, and ticketing amount include the selected baggage. Order responses and webhooks return the selections as `additionalBaggage`.

<Warning>
  Retrieve the offer again immediately before creating the order. The API rejects unavailable options, duplicate option IDs, and quantities above the allowed maximum.
