Unusual lack of snow on Feb/Mar 2018 limited our options to just a couple of places.

Access

By an offroad car rented from Georgia4you in Tbilisi.

Check that the rented car has winter tires, not just offroad tires, like ours:)

From Tbilisi Airport: a shuttle (near Didube metro station 30 GEL, 8-9 h) or taxi ($200) 

Alternatively a small Kutaisi airport with 15 kg luggage limit (100 km)

Fligth with avalanche backpacks wasn't problem with a proper documentation data-sheet of avalanche cartridges provided by a manufacturer. It can differ per airline, we checked it with them up front. 

Accommodation

We used just Booking even in Ushguli. 

Safety

There's no avalange forecast in the area. We watched snow-forecast.com weather history to understand how the snow layered in time and used avalanche backpacks and performed avalanche block snow tests.
