Here's a feel good story from the Los Angeles Times about a Delta flight attendant who gives passengers crayons and paper on flights.
"Toward the end of each flight, [Jewel] Van Valin and other crew members tape passengers' drawings to the aircraft's bulkhead so everyone on board can see them. She also maintains a revolving display of the pictures in Delta's employee lounge at Los Angeles International Airport."
The artwork has also been clandestinely displayed on walls and support columns between Gates 56 and 59 at the airport.
