For Customer willing to provide contact information
Please input the SSR CTC element as shown in the chart below. If the SSR CTC element is missing – or travel agency contact data has been entered instead of the customer contact data, the airline will not be able to notify the customer directly of irregular information. If the lack of information results in claims by the customer against the airline, (e.g. cost for travel to the airport or compensation), the airline may have recourse against the travel agency.
