I recently had a 12 hour overnight layover in Chicago, that I knew about prior to leaving, that I complained about. I couldn't even imagine being stuck like these poor travelers. 

I have also had my luggage lost a couple times in my life, once without it ever being recovered, and it's a horrible feeling! That makes me feel even worse for these people, especially considering this happened during "the most wonderful (stressful) time of the year". According to WNEM, a Frontier spokesperson said that the weather caused them to cancel about 70% of their flights nationwide, which is the reason for the baggage backup.
