I had a 777 Capt. in the jumpseat last week. He was talking about the 100 seater announcement and that ALPA didn't know what they were going to do about them. I said, "what do you mean." He said, "Would you fly Captain on it for less that your making in the right seat of the 320?" I said "We have 100 seat pay rates. It's called a DC-9 and it's more than I make, are you suggesting we give that flying away to get pay raises?" He said, "Well, no, but ALPA doesn't know what they're going to do." I said, "They better know what they're going to do or they won't be around very much longer." It was clear the he and I had a different Idea of "what to do" about the 100 seater.
