I flew AUS-PHL yesterday morning. Left Austin just as the front passed over - air temp dropped 20 degF in less than 90 minutes! I don't think the ice hit AUS until today at the earliest, but I managed to get home to PHL before it got ugly here.
My boss' boss (VP of Sales) flew SCE-PHL yesterday, then got completely stranded trying to get to DFW. We missed each other by 20 minutes at the airport (so I don't get to add to the "Running into people you know at airports" thread), but I got a chance to take him for Tony Luke's later. He managed to get to DFW today after overnighting in Philly.
