Observed from Allegiant flight 1594 from Orange County to Provo Utah. Anyone else who can corroborate this?

Just took this on Allegiant flight 1594 from Orange County to Provo Utah. We were probably 20k ft in altitude.

I REALLY wish I would’ve captured the rest on video. It appeared to expand a few multiples in size very quickly before near instantly disappearing.

People who post videos online are right - the videos don’t do it justice. I’m almost certain this was a bona fide UFO
