BANCE AIR is an airline you probably have never heard of, possibly because it does not exist as such.It is the name of a new carrier being proposed by Anglo Indian businessman Dave Bance, to operate Boeing 777s between Heathrow and non-metro destinations in India. At the present time the UK ” India bilateral allows for three British carriers (BA, bmi & Virgin) and three Indian (Air India, Jet and Air Sahara, which will shortly become part of Jet). A number of established Indian carriers are thought to be keen to take over the Air Sahara slots. Bance Air has no authority at the London end.
