Booked yesterday through Orbitz but now looking for a friend. There seem to be hundreds of flights now all around £420. You can even book directly on Air Canada for this price, I have flown with them a couple of times and really like them. Also on United. Will be interesting to see how long these flights last. I thought it might be a bit of a glitch yesterday but obviously not if several different airlines now booking at these prices. Still cant believe I got 3 flights for £1245. I will get my Flight, 21 day Disney tickets, car hire and taxi to Heathrow for less than I paid for just my flight last year!
