Cheap and quick flights from London to Geneva (Easyjet return flight less than USD 100, 90 minutes each way). From there you can reach Morzine/Avoriaz, Chamonix, and a bunch of other places in France by minibus. I recommend Morzine/Avoriaz to snowboarders.
Cheap and quick flights from London to Zurich (Easyjet return flights for less than USD 100, 100 minutes each way). From there you can reach Saas-Fee and Zermatt in three hours by train (the return on the train should cost you about USD 100). You can reach a bunch of other places in Switzerland but Saas-Fee and Zermatt each have a glacier so you can ride all year long. The glacier areas begin at 3000m (9800 feet) and go up to 4000m (13000 feet) at both resorts.
You can also look at some smaller regional airports in France like Lyon and Grenoble. It might be worth it to get to Tignes/Val d'Isere, which in my opinion is the best snowboarding resort in Europe. There is a also a small glacier area there...
Also, there are cheap flights to Innsbruck, and from there you can easily get the train to St. Anton, the mecca of off piste riding.
And there are lots of agencies which specialize in weekend getaways to all these places.
To sum up: summertime - Saas Fee and Zermatt
wintertime - Tignes/Val D'Isere
- St. Anton
Oh and you'll probably find out but here it is anyway - the trains are fucking expensive. Fly everywhere (Easyjet, Ryanair, etc.)
