But I still continue to believe there is sufficient demand between Germany and the southeastern U.S., including Florida, to justify at least a single daily CLT-FRA flight. I would not be at all surprised to see such a route eventually settle into being operated by the smallest longhaul widebody AA operates - a reconfigured PMAA 2-class 763 - but I still think the route survives with at least one daily flight.
As for PHL-FRA - as I said, I doubt the second flight will last much longer, and eventually expect it to shift to a second PHL-LHR.
