Lost & found tickets & passes in San Diego

Lost: Airline in San Diego area.

I’ve lost my Airline in San Diego, California. This morning, around 9:40 a.m., I realized it was missing while I was walking through the Gaslamp Quarter near 5th Avenue and Market Street. It’s a small, rectangular item with the word Airline printed on the front and a few travel notes inside. I’ve retraced my steps and asked at a couple of shops, but no luck. It’s important to me because it holds details for my upcoming trip and a lot of memories. I’m hoping it turns up soon and can be reunited with its owner.
