Our luggage disappeared between Moscow and Gatwick - it took 2 days to get it back - and one bag was damaged. It looks like it didn’t get transferred in Prague where we had a ONE HOUR transfer time - we weren’t the only ones on our flight this happened to. Worst - it took them 2 days to trace them at all. Check in staff in Moscow were very fussy about the 15kg checked bag allowance - 1 kg over was refused - so they watched us repack (putting heavy stuff into our hand luggage!)
Prague had a further security scan so we had to ditch the water we had carefully refilled outside the toilets. No free water on the plane(s). The Moscow - Prague leg was a mixed CSA regular / Smartwings cheap ticket flight - so better leg room etc. Prague - Gatwick was just Smartwings and a 757-800 full up to the brim and no room in lockers - woman in front of me had been allowed on with a back pack and THREE large store bags!
I will try to avoid again
