Hmmmm, It might be the case that that is just after October half term. Flights tend to be more expensive over holidays. Have a look at Flight Line- they usually have pretty good deals on flights to the US. I hope you manage to find one and get back OK. http://www.flightline.co.uk/fly-to/search.php Cheers, Jo

mainly because the weather begins to get colder around that time. That could be a good reason.
