Here are two updated charts of charter flights from Eretz Yisroel to Ukraine. One is from Nesivim Tours and one is from Revivos Tours.
Nesivim Tours: You can sign up for a flight with a down payment of $150 and pay the rest in a few weeks. In the event that the flights are canceled due to closures in Ukraine, Israel, etc – all the money will be refunded. You also must fill out this form – https://bit.ly/2Xt8x37
