Delta is definitely covering something up here. (Haven't people learned that the cover-up is always what gets you in the most trouble?) They're clearly having IT/operational issues that have NOTHING to do with the weather, and they are purposely covering it up so that they won't have to issue compensation. (I imagine some executives gleefully rubbing their hands together that these thunderstorms happened by to give them an excuse.) As horrible as this is for all the passengers, the real scandal is at the executive level, I imagine. I hope some muck-raking journalists get hold of this and attack it like a pit-bull.
