Could the TCX BJL service be a bit of a 'test the water' scenario, though I suspect it is some kind of charter for possibly travel agents??
Reading the travel press, it seems the Cape Verde islands are undergoing major expansion by UK tour operators. TUI is increasing capacity for next yesr by adding GLA as a departure point and independant operators are adding BRS/EMA, could NCL sustain a charter there in future, is it on the radar of TUI etc?
