Things are looking grim for the near-hourly DCA-ATL flights. They've canceled five of the first seven flights, and the other two are projecting multi-hour delays. I don't fly out until 6 but I'm anticipating a 2-4 hour delay. And DCA is awful for delays, it's crowded in the terminal under the best of circumstances and when flights are delayed, it's packed to the gills!
Also got a text from my boss at 1:15am (which luckily I didn't hear), he was scheduled on the 7:30pm ATL-DCA flight and after being strung along with delays for 5-6 hours they ended up canceling it. He still has to get here, I'm guessing he booked another airline for this morning.
