I'm searching for low fares for a trip in September ... I'd think I might have better luck than you! Christmas is bound to be higher, isn't it? Someone told me to wait until about 2 months before I want to go to get the best fares, so I'm holding out until July. Right now, all I'm seeing is £450-500 (opodo seems to have the lowest fares) -- not much different from what you're seeing for Christmas. I'm no expert as this is my first trip back to the US, but £500 doesn't sound so bad for the holiday season. Anyone else?
