I managed to catch the “2 for 2018” Chinese New Year Sale and with part pay with Avios, got two CW seats from LHR-PEK for @£795 each. Amusingly, this was a rerun of the sale that the has been running since 2016 and they just added £2.00 to the price, but as BA IT is the worst in the country, they cocked that up and got the decimal point in the wrong place so this year it was “2 for £2016.20.
