Hawaii-based Airlines - When to purchase?

When to book HA (LAS-MNL,RT) for July 2011? Is it better to book now or is it a little too early? I do know the exact dates of the travel. Thanks

July fares rarely go down; especially Mainland to International. If you can afford it, I would buy now.

On a side question...when should one buy interisland tickets?

Am planning a trip in late May for HNL-KOA-OGG

Tickets are about 120 each leg especially on Hawaiian...sounds expensive to me, any veterans who know the market can coach me?

I generally buy my interisland fares two weeks before I want to fly. They don't fluctuate much, but I generally expect to pay $150 - $180 for roundtrip. Sometimes less, sometimes more.

What are your dates? I see HNL-KOA prices at $79 for a random weekend in May.
