BCFT is on other side of airport / runway from Main airport terminal.
I doubt if there is any bus service around the airport perimeter. It may be a bit cheeky but you could ring BCFT when you arrive and ask if someone can pick you up
.
They are a very friendly bunch and I am sure that, if able, they will oblige...it is only 5 min to pop around the perimeter.
Failing that its a short taxi ride.
