I'm sure there must be a good reason for it, but Citiexpress at MAN seem to have gone subcharter mad which can't be helping the bottom line. I flew AMS-MAN yesterday on a Titan 146 (and very nice it was too - 5 seats across rather than the 6 that I think the Citiexpress examples have IIRC), and they also seemed to have pressed a Flightline 146 and a Titan ATR into service. Seems to have been going on for a few days.
