If the flow becomes unavailable by any means the amount of allowed 76 seat jets is reduced to 85. The seats need to be block off quickly and removed shortly there after. That is the poison pill there with the flow. So with 86 jets with 76 sets or more that leaves it very close. That is DCI wide. Currently there are 153 76 seat jets flying in the delta system. Look at you math above.

The contact allows 255 total 70 and or 76 seat jets not to exceed 153 76 seat jets until we have 763(8) mainline jets and then 3-1 for more 76 seat jets. This does not preclude DAL from awarding 70 (66) seat flying to the 255 number. The proviso on the flows details 76 seat jets not the 255 cap for 70/76 seat jets.
Make sense?
