Unknown Craft Near Airliner, Phoenix, Arizona Jan 6, 2023 UFO Sighting News

Eyewitness states: At 41,000 feet above possibly Nevada or Arizona, I looked out of the window of our Delta plane and saw something flying in tandem with us, or at least it appeared to be. The brightness increased at one point. I took both pictures and a video of it. The city and state are not correct since we were flying and that information is required to file a report. I actually have no clue where we were except it had to be in the south west region given our flight path from LA to ATL.
