If a charter operator has the Instant Book button on their listing this means that you will be able to book a fishing trip and get it confirmed instantly, as soon as you complete the reservation process.
Instant Book charters have an obligation to FishingBooker to update their availability constantly and accept any reservation immediately if they are available for a specific date. FishingBooker follows up with these charter operators on a daily basis to make sure everything is up to date.
You can filter your search to only view listings that are available through Instant Book.
There is no additional fee for confirming a reservation with Instant Book.
