It looks like LX is starting to improve their services out of GVA after long ignorance for that market.
As of Jan 2010 LX will have one A333 allocated for GVA-JFK route and also they will start to serve LHR non stop after long absence.
YUL and IAD are also being served non stop out of GVA on a code share basis.
The only thing I think LX should do is to resume a 7 am dpearture from ZRH to GVA with wide body aircraft for connecting passengers arriving early mornong into ZRH and connecting to GVA and also to switch the 10 am flight from GA to ZRH to wide body aircraft to let the passengers connecting into ZRH have the full long haul travel experinece out of GVA.
