If you want sure thing (almost guaranteed) early skiing, head for Mt. Bachelor (Bend, Oregon USA). I have been going to (late) fall ski camp at Mt. Bachelor, typically first and second week in December for the last decade and had snow each year, some years better than others.
Christmas can be chancy at best in Europe, but higher elevation resorts with snow making are the better bets. For what it's worth, check the "onthesnow.com" article:

Where to ski in September?
At the start of autumn just six ski areas are almost guaranteed to be
open for early season skiing.
Zermatt in Switzerland, which operates Europe’s highest lifts (two T
bars that only open summer and autumn) reaching 3,899m, and the
Hintertux glacier in Austria’s Ziller Valley are both open year round.
Zermatt’s neighbour Saas Fee opens mid-July each year so by the start
of autumn is already two months in to its 10-month-long snowsports
season!
The fourth option is Pitztal, with Austria’s highest lifts, which
closes in mid-May but re-opens in mid-September each year for an
eight-month season, and its sister resort, Kaunertal, operates to a
similar schedule. The sixth choice is Italy’s Val Senales that
normally opens at the start of September (subject to weather
conditions) where the cable car will lift you up to the station at
Hochjochferner in just six minutes from where a five-mile-long (8km)
downhill run is possible with additional trails available from linked
chairlifts.
Where to ski in October and November?
Austria
Austria normally has more places to ski or board operational in the
autumn than any other single country with up to eight areas open by
mid-October. The precise date each winter depends on snow conditions
but in any case many tie in the traditional autumnal beer festivals of
the region with the first skiing of the season to create one big party
atmosphere.
Along with Hintertux, Kaunertal and Pitztal, Austrian autumn glacier
ski or board options include the Kitzsteinhorn glacier at Kaprun; the
Mölltal glacier ski area, the twin glaciers of Solden; the Stubai
glacier close to Innsbruck and the Dachstein, not far from Schladming.
