Mokulele and Hawaiian airlines have both launched new programs to attract more customers in the interisland market.

Mokulele Airlines is offering a coupon booklet that consists of five-one tickets for travel to any of Mokulele's destinations. The booklet costs $267 including all taxes.

The coupons are fully transferable, with a choice of confirmed or standby travel, the airline said. There are no penalties for itinerary changes or cancellations prior to departure.

Hawaiian Airlines has introduced an interisland fare guarantee program that locks in a special $43 fare for any available coach seat on its interisland flights over the next three months with no money up front.

The Kama'aina Guarantee program allows Hawaiian's customers who sign up on its website to purchase up to 40 interisland trips operated by Hawaiian at the guaranteed fare of $43. Travel on the special fare must be completed by May 15. Customers must sign up by March 11 to be eligible for this special fare, which is subject to applicable taxes and fees.
