I hope the OP bought the ticket yesterday. Then the ticket can still be cancelled and rebought at a more appropriate fare before the 24-hour grace period expires.
I also need to go to GVA next year. For Polaris Business, the flight through EWR was in the $8,000 range. Through IAD it was in the $4,800 range. Same price if connecting in FRA instead of connecting in the US.
