Although Qatar havnt released the return flights for January 2012 if you book through Opodo or Travelup there are some good deals to be found. i.e. Heathrow Dec 24th return 14th Jan from £539 per person also there's a voucher code for Opodo at the moment which gives £20 discount which almost covers your credit card charge. Last year same flight was was selling for £800 on Qatars website. Great transfer times too.
