(FULL FLIGHT STATS AND INFO BELOW) At 20:38MST, my fiancé and I had just finished watching a movie. The window seat (23A) next to us was empty. I leaned over to look out the window and noticed a light appear next to what I believed was a star suddenly appear out of the darkness, travel to the left a short distance, then fade and disappear. I thought it was a little strange. 10 seconds later, it happened again in the same location. That's when I nudged my fiancé and chuckled to him that I'd just seen a UAP.
He leaned over and watched the same event happen for a third time and confirmed what I was seeing. At 20:40MST, I started filming out the window on my iPhone 15 pro. We watched and filmed for roughly 16 minutes, as lights would appear, disappear, brighten, fade, move in all directions, hover and seemingly merge with a fixed 'star' (light) in the sky. We were audibly excited about these lights; exclaiming each time another one showed up, but the passengers around us were either all sleeping or had their headphones on. As to prevent any commotion in the cabin, we opted to not make an announcement or draw too much attention to it. In that 16 minutes provided, we caught multiple events. The final event, which happens at timestamp 16:05 in the raw footage provided, shows a triangle formation of lights suddenly appearing then merging together to become one bright light, which then travels upward and disappears. When we landed at YYC and were deplaning, I mentioned to the head flight attendant that I caught some footage the pilots might want to see. She invited me into the cockpit to speak to Captain, who was still seated, and I showed him a clip of the triangle formation. He asked questions about when it occurred, where I was sitting, etc. He was excited and invited his co-pilot and the head flight attendant to watch the footage. They were both surprised, enjoyed it and encouraged me to share it online.
