From what I can see, currently the fare difference between Basic and Classic on that route is the same for Main cabin and for Comfort ($35 on the date I checked).
There are two bands of C+ fares corresponding to W and S fare classes (so upfare amount will vary based on W and S class availability on flights). For Comfort+ Classic, these are identified by 'C' and 'I' in second to last position of fare basis code. Comfort+ Basic fares will use '1' and '2' in the second to last position of fare basis codes and continue to book into W and S booking classes. C+ fares, like BE and domestic F fares, are dual-inventory fares. DL has updated it's fare basis code structure document for Comfort+ Basic fares.

It looks like they got the ordering reversed in the document. Note that 'C' = W class and 'I' = S class, while '1' = S class and '2' = W class. W class is the pricier fare band for C+ fares.

Hope corporate booking tools block/omit these like main basic fares.
It's in the T&Cs (also in the Penalties section of the fare rules). Fees are the same as for Basic Economy (er, Main Basic).
