Unless the merge with envoy is a non owned aag carrier refreshing the flow all owned carriers of aag have a flow of one kind or another. So to threaten envoy pilots to capitulate on the flow restrictions for the merge is far fetched. But it can be used for a merge with a non owned carrier. Again but, why would parker care, he has a flow and you go when it's time. Aag don't care if there is a fence on the flow it's bodies he wants.
