Mokulele Airlines, flush with fresh cash and a new hangar, is giving away two travel passes good for unlimited flights through September. All you have to do is "Spot Scott," Mokulele CEO Scott Durgin, in downtown Honolulu tomorrow and Thursday.

The airline will post Durgin's location to Twitter with the hashtag #spotscott. The first person to recognize Durgin and mention the promotion each day wins the pass.

The giveaway is to promote Mokulele's new “Island-Hop till You Drop” pass, which allows for unlimited flights on the airline throughout September for $299. The interisland pass comes in the wake of mainland carrier JetBlue's new $599 "All-You-Can-Jet Pass" (which, Time reports, is making some people act insane), but the idea will seem familiar to long-time frequent interisland travelers. Hawaii's "legacy carriers" (Hawaiian Airlines and the late Aloha Airlines) used to offer unlimited weekly and monthly travel passes.

With a sample Mokulele Airlines "everyday low fare" of $64 each way, you'd need to make about three trips next month for the $299 “Island-Hop till You Drop” pass to save you money. But for travelers who already fly interisland on a weekly or even daily basis, it's a pretty good deal. So if you don't "Spot Scott," you can buy your pass online until Aug. 31.

However, the "Island-Hop till You Drop" pass is non-transferable, and all flights must be booked three days in advance. Further, if you miss your flight, your pass will be suspended (unless you pay a $100 no-show penalty). Additional restrictions apply, see site for details.

Mokulele Airlines currently has a fleet of three, 70-seat Embraer 170 jets and four 208B Cessna Grand Caravans. The airline operates 84 daily departures to six cities in Hawaii.
