I got stuck for something like 5 hours at DFW during a freak snowstorm. When we boarded it was raining lightly which turned to heavy rain, freezing rain, then snow. DFW was overwhelmed with planes needing to be deiced so when we pushed back we were #41 for that. Most planes went back to the gate swamping those and so we sat and sat and sat. Eventually we left and I was happy our pilot chose to go on as most flights were canceled and I'm sure I would have been stuck there quite a while.
