Besides searching and returning information about the Passenger's reservation, the /dcci/passenger/details service can also determine (basing on the retrieved data and the internal configurations) whether the Passenger is eligible to perform the operations using other Digital Connect Check-In services.

Digital Connect Check-In can diagnose and return the constraints related to:

• Passenger check-in process
• Passenger boarding process
• Baggage check-in process
• Ancillary purchase

Each eligibility returned by the /dcci/passenger/details service informs about the following details:

• Type of the eligibility
• Eligibility code

Basing on the code the customer can understand which operation is blocked and what is the reason of that.

• Passenger can be requested to wait before some action is available as in the following situation when the check-in window is not open yet.

  {
    "eligibilities": {
      "eligibility": [
        {
          "reason": [
            {
              "property": [
                {
                  "name": "TIME_TO_OPEN",
                  "value":"380"
                }
              ],
              "category": "CHECK_IN_WINDOW_NOT_YET_OPEN",
              "message": "Segment check-in window not yet open"
            }
          ],
          "notEligible": true,
          "type": "CHECK_IN"
        },
      ]
    }
  }

• Passenger's action might be required to remove the restriction for example by adding missing address data.

  {
    "eligibilities": {
      "eligibility": [
              {
          "reason": [
            {
              "category": "PASSENGER_DOES_NOT_HAVE_DESTINATION_ADDRESS_DATA",
              "message": "Passenger is missing required destination address"
            }
          ],
          "notEligible": true,
          "type": "CHECK_IN"
        },
      ]
    }
  }

• There can be also a situation when the Passenger cannot do anything and finalizing the process using self-service channel is not possible.

  {
    "eligibilities": {
      "eligibility": [
        {
          "reason": [
            {
              "category": "SELF_SERVICE_CHECK_IN_NOT_AVAILABLE",
              "details": "NOT OK TO BOARD",
              "message": "Passenger needs to visit an agent to continue check-in process"
            }
          ],
          "notEligible": true,
          "type": "CHECK_IN"
        }
      ]
    }
  }
