The mechanics
Weight decides your seat, the price is the same everywhere, and free cancellation to 24 hours makes an early booking a free option. Here is how the whole thing actually works.

Quick answer
The short answer. Book online, as early as your dates are fixed, for the first slot of the morning, on the first morning of a two-night stay. Free cancellation up to 24 hours before means this costs you nothing if plans change, and it is the only strategy that reliably gets people into the air on this coast.
When to book
Every flight on this site can be cancelled free up to twenty-four hours before departure. That turns an early booking into a free option: you hold the seat, and if the plan changes or the forecast collapses you give it back at no cost.
There is therefore nothing to gain by waiting. In December and January the first morning slots go weeks ahead, and after two grounded days there is nothing left at any operator.
Which slot to take
Air on the West Coast is calmest before the valley warms and cloud builds. The first flights of the day are cancelled least often, fly in the smoothest air, and leave the rest of the day in reserve if the morning is called off.
Booking an afternoon slot on your only day here is the single most common planning mistake made in this village.
Check-in and the weigh-in
Arrive at the base about thirty minutes before your slot. You will be weighed — everyone is, without exception — and the pilot uses those numbers to balance the aircraft. Seats are allocated on that basis and it is not negotiable on a shared flight.
If sitting at the front matters to you, the only way to guarantee it is a private charter, which is a different product at a different price.
The briefing takes two minutes: door handles, seatbelts, and the rule about never walking uphill of the aircraft on sloping ground.
If it is cancelled
The operator usually calls or messages the evening before with a realistic read, and makes the final call in the morning. If they cancel, you get a full refund or a free reschedule if there is a slot.
If you cancel yourself more than twenty-four hours out, full refund. Inside twenty-four hours, generally not — so if the forecast looks bad, let the operator make the call rather than cancelling yourself.
Before you book
In time order, from the month before down to the morning of the flight.
Free cancellation up to 24 hours makes an early booking a free option, and the first morning slots go weeks ahead in December and January.
The air is calmest before the valley warms, those flights are cancelled least often, and you keep the rest of the day in reserve.
One night gives you one morning, and on this coast that is a coin toss. The second night is what gets people into the air.
The eighteen-minute option costs the same as the twenty-five-minute one and stays in the air the whole time.
Seats are assigned by weight at check-in. The conversation at the scales is avoidable.
They call or write with a realistic read on the morning. Let them make the cancellation call, not you.
Wondering what actually grounds a flight here? The cloud base, not the rain.

Common questions
As soon as your dates are fixed. Free cancellation up to 24 hours before makes an early booking a free option, and the first morning slots in December and January go weeks ahead.
No. Operators publish one seat price and hold it everywhere. Turning up gets you whatever is unsold, which in a busy clear week is nothing.
Not on a shared flight. Everyone is weighed at check-in and the pilot allocates seats to balance the aircraft. A private charter is the only way to control it.
About thirty minutes before your slot, at the operator's base in the village. There is no airport transfer — everything flies from the township.
Free up to 24 hours before. Inside that window, let the operator make the call — if they cancel for weather you are refunded in full.
No. Bookings are confirmed instantly with a mobile voucher.
