Why not TK? Plenty of Jews fly TK regularly. It's the most efficient way to get to Russia nowadays. And unlike MS which is a 3rd class airline, while TK isn't a ME3 or Asian airline, it's definitely on par with UA, and LH group airlines.
I've made a personal rule to never give a dime to a turkish company. Never flew with them, even when there was wide open J for 34k to the US from Israel
With erdogan's comments about Israel, and he openly welcoming hamas etc, I think it's not wise to transit in turkey these days
My 2 cents
