Service tax return for air travel agent service

Dear All, Good Evening!! I have a query related to service tax return. In case of AIR TRAVEL AGENT SERVICE, service tax paid as per rule6(7), i.e. 1.2% on international ticketing and 0.6% on domestic ticketing. How to fill the service tax return in this condition..what is the service tax value and rates?? As in this case two composite rates occurs and ST-3 has taken a service only once.. Kindly advise!! Best Regards, Mohd Hammad
