I am just booking Manchester UK to Atlanta. Those prices are insane unless they are business class.

Delta have a sale for the bookin during the next week. I had a quick look on netflights.com they show prices for a direct flight of around £600 per ticket for the last two weeks of July. Delta offer child discounts which is fair in my eyes as they are a third the weight of an adult in many cases.

Good luck

Those prices aren't too crazy, they are around normal. I think most airlines offer some child discounts, depending on the childs' age, of course, not when they are teens or beyond, I think, so I presume these kids are adult fares. It usually costs more to fly from Paris than London, so that doesn't surprise me. Flights from US around Washington DC to Paris and back are around $1200-1500 this year in July so should be more like 1000 euro, but if you are quoting fares to Knoxville, etc., I think that is just what they are this year.

YOu might be able to do a little better but maybe you are picking some bad dates and should play around with that. YOu cannot go to podunk places like Knoxville or Asheville at a decent price, that is basically adding on another local flight. But frankly I don't think 1100 euro in the summer for a RT from Paris to Atlanta is abnormal this year or will drop in price. In fact, I've seen fares around 1200 euro for that type ticket on Air France.

Fares will drop around 200-300 euro per ticket if you wait until September.

YOu can try XL Airways, they fly Paris to NYC for around 850 euro RT in July. It would probably be as cheap to fly from NYC to Knoxville or wherever than from Atlanta, but if you got a fare of 1100 euro RT to Atlanta, that might be as good as you are going to get.

This article won't help for this year, but does confirm the prices you're seeing - and provides some interesting insight into ticket purchasing for overseas flights:

It would seem that it is £350 cheaper to fly to Atlanta from LHR than from CDG in July.

You could try a low cost flight to transfer from Paris to London but the logistics are terrible.

I seem to be finding that 4 to 6 months before departure is a cheaper window but each year changes.

I found the "using a cheaper hub like Madrid" hint in article above to be interesting. We did that with Dublin several years ago, plus Ryanair, and saved a bundle.
