An article titled "Cleveland May Lose Continental Hub" was posted the other morning on
http://www.newsnet5.com
If you do a search for "Continental Hub" on this site you'll see the headline is still there but the article was delete. I read the original article and it really did not provide any details or source for this info.
Even though I fly out of CLE every week, I'm secretly hoping Continental pulls out and JetBlue turns the D terminal into their new Embraer 190 hub.
