There is a bigger issue here.
DAL is becoming ballsier when it comes to dealing with major weather events. We saw it in ATL with the storms this week, last month it was trying to run a full schedule thru NYC/BOS during a blizzard. They are pushing it to the brink and this week it all blew up in their faces. They still won't learn.
Cancellations forecasted thru Monday now, also.
