So what is the actual cost for full, uncompromising mainline parity at the DCI level?

Then back out all the redundancy and costs associated with a "portfolio" of DCI's. Then amortize all that over the CASM and you come up with numbers so insanely low that it illustrates how laughable it all is to outsource half your airline.

And like others have said, if it makes sense at the 76 and under seat level, it makes more sense at the 737, 757, 767, 787 level, right? Right?

If it really comes down to it, we can give them a break on some of the costing. Since it would create mainline jobs at an earlier entry point, we could have less than a 14% DC match. Oh wait, that's a B scale, right? Isn't that bad? Well its a heck of a lot less bad than outsourcing to the scum of the earth regionals like Hulas and JO and BB. Likewise, first year pay of 56 can be lowered for that seat only. Again, B scale? Get off the high horse because its far superior than off listing it.

And again, the total cost savings are miniscule as many have estimated using very conservative numbers like 100/hr premiums for it being at mainline and the "savings" is still very, very paultry.
