I'd like to use a SWU so I want to stick with the UA flight number.
It's possible the UA code within Europe is pushing the whole thing up.
Try pricing a UA RT to/from LHR (or other gateway) only and see if you like what you get.
If so, price a one-way CDG-LHR (or other gateway) and see what you get (on a proper carrier: BA/AF/etc.) -- should be about $100.
If this is satisfactory,
call UA and have them build that with the UA flights to/from LHR, and the AF/BA/whatever flight you pick.
