Majority fly to Russian cities like Moscow, St. Petersburg, Novosibirsk others, but which fly to cities inside each republic that makes up the Russian federation, I know of the following:
Lufthansa to Kazan in Tatarstan, a tiny oil rich Muslim republic.
Another interesting fact, Tajikistan in the only former Soviet republic without the services of a major airline
, all the rest i.e Latvia, Lithuania, Estonia, Belarus, Ukraine, Moldova, Georgia, Armenia, Azerbaijan, Turkmenistan, Uzbekistan, Kyrghyzstan, Kazakhstan and ofcourse Russia have one or more major airlines flying to their cities.
Which airlines fly to Kaliningrad
? those who dont know its a tiny bit of Russia cut of from the rest of the country and nestled between Poland and Germany, formerly it was known as Konigsburg?.
Here's a list of teh republics that make up the Russian federation, unlike states/provinces, these are small countries with in Russia, http://www.flags.net/RUSS1.htm
