While going for a sea plane ride in Maldives, you should know that there are only two major seaplane companies operating in Maldives:
TRANS MALDIVIAN AIRWAYS (TMA), which is the largest operating company of sea planes in the world and has the largest number of seaplanes in the hangers.
MALDIVIAN is the national airlines of Maldives and operates 6 DHC-6 Twin Otter
In case you find everything booked with the mainstream flying companies you may check with FLYME, the company that operates with just a single aircraft.
The Male airport has one runway for international flights and the other is an airfield on top of the waters. The later one is the place from where the sea planes fly. Here while you wait, enjoy seeing the seaplanes arrive and take off.
If you are planning for a sea plane ride days later of your arrival at Maldives, then you need to reach the airport as that is the take-off port for the sea plane rides. For your travel from your stay or the resort, you are supposed to head to the capital city of Male. For the local conveyance in the city, there isn’t much a trend of cabs which we are used to, so do plan your travel with a handful of time in hand so that you don’t miss your sea plane ride. If you are visiting the place in an ongoing holiday season, the public ferry to Male from your resort might need to be booked prior.
If you are planning an expedition to the city of Male while you go for the sea plane ride you can intelligently negotiate with the tourism taxi services. You book a drop and pick up at the Airport while you go and then comeback (if planning a return too) from the sea plane ride. The package can include your local Conveyance while you shop and explore the city of Male.
