When should I buy my plane ticket when travelling from Europe to USA in August?

I will be going to Dallas, Texas from Paris, France in August 2008 and I wanted to know when is the best time to buy my ticket.
I am wanting to buy it just about 5-7 days in advance. Because I'll have more money by then. Is that a good idea? If not, what's the latest that I should buy it?

Also* my return date will be a month after my departure

The sooner the better!! I am going to Europe in May with my sisters and we all bought ours in December for around 800 bucks round trip. My one sister didn't buy it though til like a month later and it cost her an extra 100 dollars.

try to at least purchase them a month beforehand. you can get good deals on flights out of here, into here I am not so sure... the economy is getting really tough out here, so if you do hold out awhile, I bet the prices will come down a bit... wait to buy until JUNE

(remember this is my opinion ONLY)

I check the prices regularly, this summer will be expensive. Prices are going higher and higher and it seems that good bargains will be just sweet memory from last summer. Even now it is hard to find good deal for August, so really, the sooner, the better for your budget.

The other option is to wait for the last minute deals but I do not advise you to do so, because with the summer craze surely last minute deals will not be good deals.
