In 30 days between mid December and mid January I did 117 hours block.
3 ULRs and 2 Euros
LHS 777
That's insane.
How are your rest rules defined? Is it xx hrs per calendar month, or per 30 days etc?
Here in the US, under the new rules, we're limited to 100hrs of flying in 672hrs (28 days).
I ask, because as oddly as our rule is written, it helps in a situation like yours where (I presume) DEC was back loaded, and JAN was front loaded.
