Albert is correct. And then AMEX never got it together with the, then, largest carrier, UA, either. And so it was, AMEX co-branding with DL.

AMEX and AA would have been an awesome powerhouse. Citibank didn't do that badly. You've gotta wonder what the big egos were doing when these things crashed and burned.
