Details?

You didn't say where you are flying from. ATL/NYC/DTW/MSP/LAX/SEA/SFO all can avoid any non-international legs.

Are you looking for F as opposed to BE? The Delta BE product is quite good on that trip (depending on equipment).

I do not see how your SWUs play out here, unless you are willing to go BE and that fare is over the limit. In which case you need an M fare for around $2800 and use SWUs. BUT you need to be certain you can actually use the SWUs.

Sorry for the vague reply, but it really is unclear what you need.
