I shot off an email to my contact about this and this was his reply
anyways, to answer your question....there will either 3 or 4 shuttle
aircraft being converted back to Mainline....Not sure which tail numbers
yet, the engineering and planning work is still in the writing phase at the

This makes sense as there used to be only 10 727s assigned to the shuttle when it flew DCA-LGA or BOS-LGA only. With the 16 current shuttle aircraft and the DCA-BOS service switching to CRJs it should free up that many aircraft.
