Trying to buy a ticket from FRU to NCU (via TAS) on Uzbek Airways. Unfortunately, on the day I would like to fly, buying one connecting ticket does not seem possible via their main website, but appears to be possible on their russian website...

I tried reaching out to their sales office and via Facebook, but nobody responded.

I do have an option to buy two separate tickets, FRU to TAS and then TAS to NCU, with a 3-hour layover in TAS. Is that sufficient time?
