Chaos drags on at new Heathrow terminal

British Airways cancelled a fifth of flights from its new $US8.6 billion ($A9.37 billion) terminal at London's Heathrow airport as its high profile launch gave way to a second day of chaos and embarrassment on Friday.Passengers hoping for an early end to the problems at the state-of-the-art terminal were told a further 54 short-haul and European flights would be cancelled on Saturday although all long-haul ones would operate as normal.
