I second that. I've always actually thought that the few times lifetime status is really useful doesn't make up for the risk that the LTPE program is revoked or that Flying Blue files for bankruptcy. Rewards generally have higher value when immediate.
Otherwise, cheap european J is the way to go for massive XP earnings. There are routings like DUS-CDG-TLV return for around 400 to 500 euros that will grant you 78XP (the CDG-TLV is a bit above 2000 miles and thus falls into the Long Haul 1 category). And the destination leaves you the opportunity to have a sunny week-end.
