When I say Transportation Module I Mean SPRO > Logistics Execution > Transportation in SAP ERP ECC6.0
Ticketing System means to book online tickets and view schedule etc? We can use SD module for selling tickets but yes for Tickets reservation and flight schedule etc I have never seen such thing in ERP and I am sure you have searched everything on it. If you don't find any solution then you should contact SAP directly. They might have some solution for it.
Airline industry is world's biggest industry and how could SAP leave it orphan without releasing some industry specific solution 
Did you search everything and didnt get anything?
Thank$
