Bill Boyer, a former Alaska Airlines baggage handler and Lakewood espresso stand entrepreneur who now owns Hawaii’s Mokulele Airlines, says his growing airline has a new financial angel.

Dorvin Leis, head of Hawaii’s largest mechanical construction firm, has invested several million dollars in Boyer’s commuter airline, the airline said Monday.

Boyer made his fortune by inventing and marketing a portable digital movie player for the transportation industry. Boyer sold his digEplayer to a Salt Lake City firm and bought Mokulele.

That airline, now has a deal to serve as a feeder airline for a new Hawaiian carrier go! owned by Mesa Airlines.

Mokulele is investing in four new single-engine, 9-passenger Cessna Caravans to fly its routes among the Hawaiian Islands. Service began earlier this month on go!Express’ first route.
