Good deal from Fiji Airways which allows you for a stay in Honolulu + a stay in Nadi, Fiji. Good opportunity to see 2 places in 1 trip. Fares include bags, meals and seats. Dates from May to September.
This deal requires purchasing a multi-city ticket. Outbound flights have a stop in Fiji and Kiribati, with a return stop in Kiribati. It's possible to reverse this if you prefer, visiting Fiji first and Hawaii second. The sample search includes a 2-week stop in Hawaii, but it's possible to vary the length to fit your interests.
