Go ahead and call me a doubter, but I can't find any reference to this on the Pinnacle site. Nor can I find it on the Mesaba or Colgan website. Also, not mentioned on Yahoo Finance, usairways.com, or airportbusiness.com. I call BS until I see it on one of those sources.

Only thing I see that MAY confirm this is, when attempting to book a seat on LGACHO/IAD/MHT for some dates in March, the website doesn't give an operating carrier. Doesn't say Colgan like it previously would have, but shows an SF340 with no operator.
