Do the inter-island flights in Hawaii use
- a ticketing model like the lower 48 states (purchasing far in advance is massively cheaper, high fees to change tickets)
- or a "bus model" like the inter-island flights in Trinidad and Tobago (show up, buy a ticket, get on the next plane)?
I'm planning an extended trip to the islands, and I'd like to maximize my flexibility by not buying inter-island flights until I have exhausted the charms of the island I'm currently on. But, not if it costs me a fortune to do so.
