Swiss has three a day to DME. I picked next Wednesday 14th at random but this would appear to be the regular weekday sechedule:
LX 1334 Zurich Moscow (DME) 07:00 - 14 Feb 14:00 - 14 Feb
LX 1326 Zurich Moscow (DME) 12:30 - 14 Feb 17:55 - 14 Feb
LX 1324 Zurich Moscow (DME) 20:35 - 14 Feb 01:59 - 15 Feb
