I'd love to see it all happen. The MM thing makes perfect sense to me. As for LAX-FRA that would be fabulous too--nice to be able to get to Europe in BE without stopping. I've never taken AFs LAX-CDG service, so I don't know what their loads are like and why/why not DL would intro their own LAX-CDG. I do know that LAX-FRA was once an important route and they still keep it as "direct" service on DL 106. That said, I heard a rumor two years ago that we were getting LAX-LGW so who knows.
Even if they don't pan out, nice to have a favorable DL rumor for a change!
