On my first trip through French Polynesia I treated the inter-island flights like an afterthought, and I paid for that with a lot of avoidable backtracking. The Air Tahiti Pass changed how I plan, because it bundles a set of Air Tahiti inter-island flights into one product instead of a pile of separate tickets. Air Tahiti is the domestic airline that connects Tahiti, Moorea, Bora Bora and the further archipelagos, and the pass comes in named versions built around different island clusters. I've learned most of these tips the slow way, by getting things slightly wrong and fixing them on the next trip. Here is what I tell friends before they book.
Pick the pass that matches your islands
I always choose islands first and then match the pass to them, rather than the other way round. The named passes — Discovery, Bora Bora, Marquesas, Australes and Lagoons — each cover a different group of islands, so the right one depends on where you actually want to go. Routes and schedules can change, so I confirm the current coverage and timetable with Air Tahiti at the time I book instead of trusting last year's plan.

Pack light, because the planes are small
The inter-island aircraft are modest, and baggage allowances are tighter than on the long-haul flight that brought you in. I travel with a soft bag I can squash into a small space, keep anything fragile in my carry-on, and leave room for things I'll pick up along the way. Weights and allowances vary by fare and can change, so I check the current limits before I fly rather than guessing.
Build slack into the schedule
The thing I wish I'd known earlier is that a relaxed itinerary beats a packed one here. I leave a buffer around connections, avoid planning a same-day inter-island hop before an international departure, and treat weather as a normal part of island flying. When a flight time shifts, an unhurried plan absorbs it; a tight one falls apart.

Frequently asked questions
Is the Air Tahiti Pass worth it for a short trip?
If you only plan to see one or two islands, separate tickets may be simpler, but once you're visiting three or more the pass usually makes routing and pricing easier. Compare both for your specific islands, since fares and rules vary and can change.
How far ahead should I book?
I book as early as my dates are firm, because popular routes fill up in high season. You can confirm current availability and any booking deadlines directly with Air Tahiti when you reserve.
Can I change my flights once I've started?
Some changes are possible depending on your pass and fare conditions, which vary and can change. I always check the specific terms at booking so I know what flexibility I actually have.
