Yup. Pretty much continuously since Delta originally sold Compass to TSH in 2010, including several rumors Delta was going to buy Compass back. Read the old threads if you want the details. Hasn't happened yet though. And even if it did, it'd likely take A COUPLE years before any of the changes filtered down to the line flyers. Alaska bought Virgin a couple of years ago, and their seniority list integration still hasn't happened yet.
