Not what you are thinking. I’ve taken a Virgin Atlantic flight to London twice and I’m telling you once you fly Virgin you’ll never look at other airlines in the same way.
Now you can fly to London for $499 through the middle of February. Not only $499 for the round trip tickets, but also 6 nights hotel and breakfast. The last time I also got a discount on the Original Tour as well (hop on and off the bus all day all over London, plus some interesting facts and history, I enjoyed it very much).
