Cheaper to buy ticket to London now or later?

[Coolers]

I'm planning to go to London in October and the cheapest ticket I've found right now is $400. Will prices change dramatically the later it gets? I know that October is low season, but I'm not sure how this will affect plane ticket prices.

Well first thing is you haven't mentioned your origin city from which are you leaving. The second thing is the prices are keep on changing so I need to check how low can it get but that requires your origin city.
