Nothing to do with WN, well it does as it was a deciding factor into using WN, but it is my magical bag story. I will shorten this to a point that it may not make sense as the whole thing takes about 30 minutes to tell.

PWM-PHL-SDF on US. PWM-PHL cancelled. Rebooked PWM-???-SDF w/change in New York, CO out, DL to SDF. Arrived EWR connection was in LGA, 30 min connect. Rebooked DL EWR-CVG-SDF on DL w/only 20 minutes to catch flight. The CVG-SDF flight was the one I would have been on out of LGA. Only 5 of us on flight from CVG to SDF (reposition flight). Arrive SDF and my bag is on the carousel.

Even WN can't do that.
