I flew by S7 from Kazan to Moscow.

I often think people in the west are too harsh on Russian airlines safety records. Russia has some difficult whether conditions and also a huge number of flights, so the chances of crashes are higher. But I did notice stuff on the S7 flight I took. Firstly there was no computerised checking in system, it was done by paper and such. Then on the flight there was luggage that should have been in the hold (big suitcases and lots of them), piled into the empty aisles. Is that allowed?

Because you are allowed to keep small knives and stuff in your main luggage, because it will be out of your reach on the plane. But if peoples' main luggage is in the main cabbin they could retrieve it.
