If you've enquired about a certain trip or date, captains can send a pre-approval to let you know they are available for your request. This means you can book the trip without waiting for them to approve your booking request.
If you receive a pre-approval, you'll have 24 hours to click Book Now and complete the booking process to confirm your reservation.
If the offer expires, you'll still have the option to request the trip, but will need to wait for the captain to approve your request.
Make sure to always check the booking details and price breakdown before submitting a request or confirming a trip.
