Beginners Question on CRUD of delivered flight Model for Travel Agency info.

I am using the delivered flight model for a simple CRUD application creating a travel agency

The Read, Updates and Deletes are working perfectly.  with the following URL's

http://usphlvm2248.phl.sap.corp:55080/sap/opu/odata/IWFND/RMTSAMPLEFLIGHT/TravelagencyCollection('00000055')/

However I am having problems with the Create.  After reading the documentation, it suggests that one would simply read a record and then use that as the request.
