Service tax for air cargo agents

Dear All,

I am working with a logistic company.

My Co. transports goods from port to port by Air.  We have contract with the Airlines on  commission basis. Air lines has provided it's  Air way Bill to us. This bill is given to the customer on colection of goods to be transported,  Server tax @ 12.36% is collected per transaction / per Air Way Bill on total freight charged.

My Question is, Should my Co. working  as "Agent" for Air Lines, Collecting  goods from Customer on it's behalf & issuing its dcoument (Air Way Bill)  can consider Service tax collectad as Input for its Service tax Return.?

Pls post your replay ASAP.
