Cave might be a bit extreme but since the interim agreement seems to give about 75% of what the company was asking, there clearly was a recognition that the company controls more than ALPA previously wanted to admit.
There is a quote from a DL pilot who visited St. Patrick's cathedral in NYC in a paper Sunday. He said, "I didn't pray for myself and I didn't pray for ALPA. I prayed for Delta. I want this airline to survive." That statement says volumes about the fear and motivation of DL pilots. I think they will be rewarded for their sacrifice in good time.
