Supposed to fly DCA to JFK Tuesday morning to catch a JFK-HKG afternoon flight. They are predicting 1 inch of snow on the ground by Tuesday morning in DC (not NY), with no snow fall by the time we're scheduled to leave (around 9:30). What are the chances (get out your crystal balls everyone!) of our plane (ERD) actually getting off the ground and us making our 1:30 flight in JFK? Is there anything we can/should do now proactively to make sure we make our connection. I hate the stress of winter travel!
