One thing is clear - competition to London seems to be helping. Prices are generally down and the Saturday night stay rule seems to mean nothing in terms of lowering the price. Finally a break for us small business people!
Can't say the same for Paris where the nonstop prices are still in the $900s vs the $600s without the Saturday stay, but I'm sure once Easyjet starts flying that route, prices will rationalize further.
What I really don't understand is why AF/KL don't increase frequencies. Instead of adding an extra flight AF seems to have moved their 6pm flight from CDG to TLV to 11:30pm, which was once the only civilized way of getting back to TLV from the western US. Now if I have to do a double redeye, I'll do it on BA or LX (or TK from Los Angeles).
