Just booked through Expedia for 24 Jul to 7 Aug on US Airways via Philadelphia. Family of 4 plus full-size car with Hertz for total of £1917. Sometimes it pays to wait!

Hurry, though. I don't think that fare will be around long. And dates a few days either side seemed to come up at quite a bit more. I must have just been lucky to hit on the right dates.
