Once Compass was closed that provision ceased to be available triggering the reduction. This is not in dispute. Delta even tried to argue the reduction could be in block hours and not actual airframes. We are still waiting on arbitration on that claim. The company said they were in compliance because of the compass closure and the RJs were removed when in fact they weren't. They then claimed flight time was removed. Either way they intended to comply with the 35 jet reduction evidenced by their memo stating they were in compliance. Once removed, there is no mechanism for a new agreement other than a 4 party LOA for whatever terms we negotiate. LOA 9 was proof itself of the need to renegotiate because it was the mechanism to continue the flow for 35 jets after Trans States purchased Compass. Trans States would not have made the purchase if the jets and flying were subject to cancelation. One could argue it was a 5 party deal. Management could have done that again when LOA 9 died but it would be a new agreement with new parties. There is no provision for unilateral substitution after the fact without agreement.
