Pudoc, No, it's not...ops are like that.
For ex: in one night you will have a duty of 11h but fly only 4hrs...
You start from an outstation at 2000z, coming back to Lej at 2200Z, have to wait up to 5 hrs in Lej before doing an other small leg or leaving Lej at 0200Z for two legs... as it's european flight, it's not very long legs.
From Lej to Vitoria or barcelona, it's 2h20 block... but if you are going to Copenhagen, Francfort, Warsaw, Paris,... it's only 0120 block time.
And if on top of that you are doing some stby....
