Well, BA's starting their GVA's on DEC 18th.
But this is only a ski-season flight. It ends end-March 2011 again. So the only year-round service LCY-GVA will be Swiss. There are plenty of ski-season-only connections from the UK to GVA, e.g. EZY's STN or BHX, the tricky task is to operate it with decent yields over the summer. It's not impossible of course BA will rethink now and try year-round once again, or possibly AF will put Cityjet on this route. BaBoo was code-sharing with AF.
