Sorry to be a pest on this board, but my wife and I have locked in June, 2012 for our return to Paris after my 35-year absence.  I'm now looking at about $1450 r/t per person.  Are there any times between now and then where the prices have historically come down significantly - if only for a few days?  Is this about normal for the JFK/EWR/BOS to CDG routing.  Montreal and Philadelphia could be options as well for us.
Thanks.
