Virgin Atlantic has launched another reward ticket sale between North America and London where round trip economy class reward tickets can be had for only 25,000 Flying Club miles. This is a 10,000 miles discount for most of North America but for Vancouver it is even better as these reward tickets normally cost 42,500 miles. Now, VS does charge fuel surcharges on their reward tickets and the total taxes and fees for an economy Vancouver-London reward ticket is £260 (about C$423). For more details or to book this offer please see here. Reward tickets must be booked by Sep 20 and according to VS the best availability on this route is Sep/Oct 2013 and Apr 2014.
(The offer is only accessible on the UK version of Virgin Atlantic’s site so if the link doesn’t work because it automatically places you on their US/Canada site just switch to the UK site on the upper right hand corner)
