100k is not bad. However, assuming you can buy revenue tickets for around $1300 you really don't get a great value out of the points.
Still, what is your question? You wanna post the dates you're booked on before you cancel them so on the chance they go back to inventory someone can grab them if they want?
I haven't seen any Delta $1300 to Israel from Florida. The lowest has been $1650-1750 (which is a ripoff IMO).
Also, while 100k isn't great (I found 85k last trip), I constantly monitor what's available and it's the best I've seen for many months (almost a year). Delta redemption generally sucks.
