some people will pay that little extra for a non stop flight MAN-HKG, just like down south.... LHR-HKG
hearing from family and friends and other passengers needs, people like to fly but are scared from sense direction, worried getting lost, looking for flights/gates or language barriers from a transfer flight.
There is nothing better to board a flight, then get off at the destination.
But i know people wont get on a BA flight cause of the luggage allowance and the price you pay over service.
