For example, I was able to find seats departing Los Angeles LAX on Saturday, December 29, returning from London LHR on Tuesday, January 8.
You'll find a few other dates available for travel around New Year's departing December 24, 26, 28, 29, 31, or January 8. Return from London between January 8 and February 8.
There is more availability with slightly lower $485 roundtrip fares starting in mid-September. These fares require a stop in Switzerland on the return flight. Nonstop flights in the fall are available for $524-$544 roundtrip. A 7-night minimum stay is required and there is a maximum stay of 30-days.
