Depending on where you're staying, you might just want to fly straight to Heathrow, though. Although judging by a recent thread you wouldn't be able to check your bags through from Paris to the US, which is tiresome.
About 18 months ago I was in Paris for work and was heading off to Madrid on a Friday afternoon for a jolly. I decided to fly CDG-LHR on Friday morning as I thought this would be the best solution to connect to LHR-MAD rather than the train.
It was not. By the time I'd
driven to CDG
made my way through the zoo that is T2B
waited in the lounge
bussed to the aircraft
boarded
waited for a slot
taken off
circled over Essex
landed
waited for a gate
waited for the guidance system
disembarked
got the shuttle to T5A
queued for BP check
queued for Fast Track (oh, how we laugh) security
navigated through the crowds to the F lounge
it would have been far less stressful and probably just as quick to get the Eurostar to St Pancras and then the Piccadilly Line to LHR.
