Q1. How and where to use Book method in Air API

Solution Book method is to hold the Booking of Non LCC airline. Every Non LCC airline must be Hold first before ticketing. It will not work for LCC airline because LCC airline is ticketed directly.

Price verification is done before creating a booking and PNR No. is returned in case of a successful booking.

In case of Price change or Time change, you will get new fare and/or new time in Book response with IsPriceChanged node and/or IsTimeChanged node set as ‘true’.The price comparison is to be made at the client’s end, and Book request needs to be sent again with the updated fare and/ or updated time. Passenger’s Date of Birth and Passport details are optional in book request wherever applicable. However, if not provided in book request then the same needs to be provided in Ticket request

Q2.Where we get last ticket in book method

Solution In book response you will receive node LastTicketDate before that ticket date you have to call ticket method.
