Betty girl, bondim, thank you for the information.
bondim, yes we have a time limitation 80 hours per month. This is law.
With crew member confirmation up to 8 hours per month might be added as overtime.
Totally in the frames of law maximum 88 hours per month might be reached.
Minimum rest between duties is 12 hours.
Maximum duty time might be up to 16 hours in case of double crew. In case of standart crew (as an example 4 cabin attendant in Boeing 737-500 ) the 12 hours per duty is allowed.
BUT!
Usually in the russian companyes like my girlfriend works unformally asking to work up to 110 hours per month. In principle crew attendant may disagree with this overtime, but it's not welcome by management.
Formally for all control organizations airline will provide the information with max. 88 working hours per crew.
Because a lack of crews in Russia, the is no days off, especially in summer time. It means that crews have a rest only for sleep.
This all i mentioned is mentioned for at least Transaero airline. (

Let me know if you have an additional questions - i'll try to answer asking my girlfriend first =)
