This service allows the airline to build and update a list of passengers associated with an itinerary. An airline can collect passenger details from the passenger, and then use this service to associate the passenger details with the itinerary while it is stored in the user session. 

An airline can use this API to display passenger details for the passenger’s review just before initiating at any time after an itinerary has been selected and a /purchase POST operation.

German Child Passport (Kinderreisepass) Numbers in the Passport Field 

An enhancement to the /passengers service that allows passengers to recognize, accept, store, and transmit 8-character German child passport (Kinderreisepass) numbers as well as standard 9- or 10-character passport numbers. 

The airline is able to transmit the German child passport (Kinderreisepass) number to authorities in the correct length and format to meet ESTA requirement.

Highlights 

Airlines can accept German Child Passport (Kinderreisepass) Numbers in the Passport Field with the following sequence of Digital Connect service calls: 

1. The airline calls /products/air/search POST and obtains a list of flight results with connection information. The airline formats this information for display to the user. 
2. The user can continue shopping by selecting flights. 
3. The airline prompts the user for passenger details (including passport information - Ealphanumeric format). 
4. After an itinerary has been stored in the session, the airline calls /passengers POST operation to add passengers to the itinerary. When the user completes the itinerary and decides to purchase, the airline initiates the purchase and ticketing process by calling /purchase POST; if authorization is successful, the /purchase service creates a PNR, EMD(s), etc. Purchase service adds blank spaces for the German Child Passport number to the passport format. 
5. The response indicates whether the purchase is successful. The airline formats this information for display to the user. 
6. The airline can call /pnr GET to PNR details, which can be formatted for display to the user.

Support for three-letter country codes

Digital Connect utilizes two- and three-letter country codes in /passengers and /purchase services enabling passenger to use the codes in their travel documents, profile data, and payment data to ensure the proper storage and retrieval of relevant information. The use of country codes also means that DC does not validate country codes' presence in DC database, instead, country code information is validated by DC downline services.
