Q: Is there a place at Sea-Tac for storage?

A: Ken's Baggage Storage and Rentals, a staffed service on the Baggage Claim level between carousels 12 & 13, offers storage for everything from a small set of keys to a bicycle. There are no self-service baggage lockers at the airport.  Visit the website at www.kensbaggage.com.
