If you're counting on flying away from Ukraine's neighbour after an attack like that, that's already not going to work. Flights were cancelled for over 2 days and only slowly restarted after 9/11. And that was basically nothing in comparison. In reality airports close to the Ukraine borders are already used by the military flights which take priority over civilian traffic. Main roads leading that way see regular military traffic.
The extra problem with booking the flights is that if there's a nuclear attack, the available options will not be updated immediately - you may book a ghost flight and then again have to fight with everyone else for a place on the new schedule.
Sorry, I don't have a good positive suggestion for transport. But if you really want to make a good plan, I'd check: where to get food directly from the farms in the area (there will be a run on the shops like we've never seen with covid), and where the local underground shelter is (most towns around that area have buildings from the times when bomb shelters were common - you can even see the signage for them sometimes), and... I guess figure out what you'd do in case of temporary martial law.
