From what I understand, all flights across the nation were equally impacted. My connecting flight was delayed, but ended up leaving right before my flight landed. Interestingly, there was a very, very long line at the ticketing counter of Delta this morning. I asked a few passersby if they were put up at a hotel like me. Every person I asked was in the same situation.
