In reply to dsh:
I think some realism is in order here and don't want to sound too negative BUT likely to be pricey and potentially spend 2 days on travel.
Depends on flight times of course, but then need to hire car or go by train, buses less convenient. So GVA then train to Zermatt, Saas Fee, Verbier possible or ZRH to St Anton by train and can get accommodation for w/ends in these resorts. French resorts less likely as they are geared up for full weeks (Have managed with Chamonix, mind). Then return.
Best I've managed is late afternoon EasyJet LTN-GVA, hire car, stay in Visp, then up to Zermatt early next day. Return good as leave Zermatt in afternoon, car to GVA, flight was 9 pm and worked OK. Another time MAN to ZRH then train to St Anton, but took up whole day with travel out and day back.
You don't mention how much skiing you've done but can be hard to find your way round a new resort for 2 days, especially as weekends are usually very busy with locals.
Good luck, hope you find some good flights, and am interested in what you find! Mike
