Cheap flights from Tbilisi, Georgia to Israel

They are "currently" in the Caucasus, and they are looking for a flight. Meaning sometime in the not too distant future, likely before Oct 18th. Therefore it IS of use to OP.

Therefore it IS of use to OP.

You got me wrong. I was saying the question whether or not flights will exist in October or November is not of any interest to OP if they are flying in September - as in that case they probably couldn't care less about whether or not there are any flights in November.

If indeed they are flying in September, Yerevan is the best option (visa, price and connection-wise). But as OP hasn't posted back in 2 days, I doubt they still have an interest in our discussion.

Fair enough

I've made this flight from Baku and Yerevan on Austrian Airlines and the cost r/t is $650. If you're coming on a one ticket be prepared to be stopped.
