As I mentioned in the TP thread and in the Premium fares sub-forum, the CDG fares seem to apply to most US destinations, with only a 14 day Apex requirement and a Sat night stay. Very unusually there are no seasonal restrictions whatsoever. £1500 in I class to the US for the entire next 355 days is a good deal. There is also a (seemingly separate) fare sale in business to other longhaul destinations ex-CDG (ex EZE, CPT)
