That's very true, I would almost argue it could be construed as "false advertising" in a way. They do disclose it, but it's certainly not advertised. Something I wonder about this Colgan crash is if congress might be interested in forcing airlines to do the flying they sell their tickets on, at least domestically.
Thing is, they have an out in regards to and kind of false advertising. As you know, when you buy your ticket online, if one of your connections or the flight itself is the codeshare partner, it does have the tiny asterik next to it pointing you to the fineprint at the bottom of the page telling you who the actual operator is.......typical fineprint though. It's their "out" for anyone saying they didn't disclose.
