That's the best news I've seen out of negotiations since being assigned a favorable mediator. We're in our 5th month of mediated negotiations and the mediator has already declared that enough progress isn't being made. Now he's doubled-down on the number of meetings per month just as we're passing into the economic sections of the contract; which should stall out, hence the SPSC drawing up volunteers for the impending strike vote. This isn't progress in terms of contract language but it is certainly progress in the RLA process to reach self-help ("strike").
