The current Twin Otter fleet is maxed out as it is.
1 Islander operates from Lands End - St Marys
1 Islander in for check at Lands End.
The other Islander alternates with the Lands End - St Marys Islander throughtout the day.
1 Twin Otter on the Newquay - St Marys.
The other two operate the BRS, SOU & EXT throughout the day.
The S-61 is almost always full - about 26 seats - BIH make £2000 for every flight, £1000 of that goes on fuel and the chopper, the rest goes on staff wages and the upkeep of the heliport, hence the loss making - so even though the flights are full, they still make a loss becuase of the increased price of fuel.
