Oh, so you have airline tickets good for travel this weekend? Uh, yeah, about that: NBC’s Ann Curry — yeah, I like Ann Curry, let it be — tweets an NBC News report that United Airlines will cancel a whopping 500 flights today due to the weather, a good majority of them in and out of D.C. Delta, American and Southwest also have pretty much brought things to a halt today, as well. WJLA/ABC7 reports that Dulles is struggling to even get one runway open; similarly, DCA currently features a lone operational runway and will be closed until 1 p.m. Visibility is also pretty close to nothing in the air at this point. All that, plus one has to figure out how to actually get to the airport. So kick back, grab some hot cocoa, and prepare yourself to be spending up to an hour on hold trying to rebook your tickets — we wish you luck, waylaid travelers.
