There’s currently an amazing sale (possibly mistake?) going on right now that can get you from Los Angeles to Madrid on SkyTeam airlines for between $1400 and $1500. You can search on ITA Matrix to make it easier to find particular flights, but I went straight to Kayak to book flights. This is also available from other west coast cities.
If you find LAX-CDG as the first leg, you’re pretty much guaranteed to be on the Air France A380, which is a great flight to be on. I might prefer KLM/Alitalia as their seats are a bit better in my eyes. This is one of those deals where you’ll want to book now and ask questions later, because it won’t last!
I am going to try to find something that works out for me and will probably book it. It’s honestly too good to pass up!
