You have to delay negotiations for at least a year before the RJ cost model mirrors mainline more. DCI is un-fuel-hedged, and is paying almost $2 less per gallon. The savings of DCI is worth more than the cost of the entire mainline pwa. Furthermore, the customer service scores with the exception of gojet are the same as mainline, with Compass actual being ranked a superior product to mainline(JD powers).
The RJ fight is going to require the solidarity of the entire mainline and DCI group, to reel it in.
