Nice little sale with Air France/Delta and Virgin Atlantic between Geneva and Miami. As these are sold under Air France code-shares you would earn Double XPs till year end make this an attractive deal for FlyingBlue members.
GVA-CDG and CDG-LHR give 30 XPs each, 60 XPs for LHR-MIA, MIA-JFK just 12 XPs with 60 XPs for JFK-CDG and 30 XPs for CDG-GVA for a total of 222 XPs
This would give you instant Silver status and leave you 58 XPs away from Gold Status.
