The word "flew" in your question is a bit confusing, I guess you mean where KLM and Swissair fly their MD
-11s NOW because you want to spot or fly them at LAX
Swiss, the follow up airline of Swissair, retired their last MD
-11s in 2004.
KLM will continue to fly them for about 10 more years. SFO
is usually an MD
-11 destination. Their fleet is mainly focussed for low yield O/D flights like the Antilles, Latin America and mid Africa.
