seenitall, Pat+, and Kacee - Thanks for the detailed and quick replies!
I'm going to take your advice and take the BA flight CDG-LHR at 10:30 which should give me enough time. If I can't make it in 3.5 hr then it wasn't meant to be.
Pat+ I brought up the Premier Gold status because I read that a 1K got an Acces No1 card even though he was flying in Y. Just wishful thinking.
Kacee - yeah easy jet's carry on baggage allowance is just one unless you get the XL seats.
