British Airways and airports operator BAA said on Friday they would move a new phase of long haul flights to Heathrow's Terminal 5 building on June 5.

The two companies last month postponed the move to "at least June 5" following the chaotic opening of the new terminal, which saw flights cancelled, passengers stranded and baggage lost.

They confirmed flights to and from eight long haul destinations would now move to T5 on that date, including those to New York and Beijing. "Terminal 5 is now working well," BA Chief Executive Willie Walsh said in a statement.
