We have a number of fees that our advisors choose to absorb instead of passing the fee along to the client for our service desks. For our air desk fees, we can enter a format into Sabre that automatically adds the service fee to the advisor's statement. We'd like to do that with other fees, and it would be great if we could use a booking line to do it. For example, if an advisor asks us to create an insurance desk quote and they're going to pay the fee out of their statement for our services, we would create a booking line within the trip that it corresponds to and then the fee is automatically added to their statement. It is nice to see the fee within the trip so the advisor can determine a client's ROI. The advisor can assess if they are constantly paying for insurance desk fees, but the client never purchases insurance if they should keep absorbing that costs or if they should pass it along to the client. They can also see that they invested a small amount to get a larger amount of commission if the purchase is successful, which then promotes our internal service desks services. On the flip side, this saves our internal employees time because we don't have to manually track and then enter the fees as an expense every month on statements, it is done when we create the booking line within the trip.
