Under "open skies", it's quite simple for someone like LH to come right in if the traffic warrants. Two things to consider. Firstly, with the reduction of capacity (and elimination of the hub) at PIT, the flight becomes O&D (point to point). At that juncture, you can't support so many dedicated seats each day. Secondly, if Bayer has that many people traveling each week, they might resort to regular company flights (charter) a couple of days a week. When they first bought Chrysler, Daimler ran a regular flight right to Oakland County Airport (suburban Detroit) on a company owned A319.
