As a Service Provider, you would be obligated to honor your Listing Fee as on the date of trip activation/service confirmation by the operator.

The only exception would be for Fuel Listing. Only for Fuel Listings, due to the frequent changes in fuel prices (on a daily, weekly or monthly basis), the fuel price available in the system as on the date of flight activation is used in the estimate. The Operator would be invoiced based on the your Fuel Listing Price prevailing on the date of flight.
