Popular local mascots are helping San Diego International (SAN) educate passengers about rules and regulations of the Transportation Security Administration.

The San Diego Zoo’s Bamboo Bear, the San Diego Padres Friar, Johnny Thunder from LEGOLAND and Shamu from SeaWorld tell travelers what they can and can’t bring on a plane.

The four one-minute vignettes will air continuously at SAN’s airport security checkpoints starting July 4.
