The passengers paying for their pending AEs have an option to split their payments into several installments which is optional. In that case, the passenger must send a request to process their payment as installments.
Digital Connect Check-In provides information on the various available installment options for a passenger, based on the AEs and is allowed to pay accordingly. The following list includes all the important details which helps the passenger decide on the appropriate installment option:

1. Total payment amount
2. Installment amount
3. Interest amount

4. Interest rate

5. Additional payments (e.g. taxes)

Support installments in /dcci/pay Service

The passengers while paying for the ancillaries with their credit card are given an option to pay through installments instead of paying entirely. 
In this process,  the passenger can retrieve the different installment options and decide on a particular one; subsequently,  this information is provided to /dcci/pay service to complete the transaction.
The installment options must be retrieved before calling /dcci/pay.

Note: 
The passenger who is chosen for AEs must be the same passenger for whom the installment payment option is calculated, else the request will be rejected.
Also, the credit card through which the passenger will pay must be same as the one that is used to calculate the installment options. Otherwise, the request will be rejected.

Enhance Handling Interests for Installments 

The payment options in the form of installments will include an interest amount. The AE for the interest amount is created and included as part of the payment process.
