I'm not usually anti-El Al, but I honestly can't remember such a dumb sale in a long time. To sum it up it's a $100 discount RT, only from the US (not vice-versa), and the entire span of departure dates is 44 days (including Fridays and Shabbos).
Sorry El Al, I thought you'd do better than that. (especially considering the splash pre-sale email they sent last week)
