Exclusive: Date revealed for first scheduled departure of Boeing's 787 'Dreamliner The world's most advanced plane is finally set to take off from Heathrow. The Independent has learned that the first scheduled departure of the Boeing 787 is set for 3.05pm on 14 December. The so-called "Dreamliner," owned by Qatar Airways, will begin daily flights to Doha - but only on one departure a day. The remaining four are conventional aircraft. The plane is currently shuttling between Doha and Dubai four times a day, enabling crews to become familiar with the plane. The 787 promises a dramatic improvement in passenger comfort, with more space, bigger windows and air pressurised at only 6,000 feet rather than 8,000 feet. The first advertised departure by a UK airline is on 1 May next year, when Thomson Airways starts flying from East Midlands and Gatwick to Cancun and Orlando. British Airways and Virgin Atlantic also have orders for the new jet.
