Actually there's one issue here though, which is that Delta does not have direct CDG-SFO flights. There are two alternatives, flying CDG-SLC-SFO/SJC with TATL segment in 767 with flatbed seats (which are, obviously, better than angled NEV4

) but SLC-SFO/SJC segment will be about ~ 1 hour in a recliner seat (for non-US flyers - think premium economy class). Otherwise there is CDG-SEA-SFO/SJC with TATL segment in 777 (no D1 suites), with SEA-SFO/SJC being ~ 2 hours flight in a recliner seat.
