If I can remember correctly, Delta had 3 737's land at BWI
this afternoon within 20 or so minutes of each other. I could be wrong, but was surprised to see that many. BWI
ATC seemed to handle it well even though there seemed to be a parking lot of planes sitting on the de-icing ramp with engines shut down.
EDIT: The groundstops in New York didn't help either...
