I think the fact that this is a holiday, and therefore privately funded from a presumably normal budget, changes things. If booked on LX then you can expect a rebooking on LX or LH. Tomorrow's GVA-ZRH-RAK is at least on A32x metal so should be as safe as you can get. I was looking for flights on the basis of a business traveller desperate to get to RAK before the cilent notices...
