Thanks for the data, Herk!
What I've been seeing is the shoehorning of 4 duty periods into a 3 day trip (that only pays 15:45), 5 duty periods into a 4 day trip, etc. Again, flying one redeye is fine but to have multiple circadian shifts in one rotation is less than ideal to say the least.
It seems to me if our contract had verbiage that a rotation would pay the greater of a 5:15 ADG or 5:15 duty period minimum, it would provide a negative incentive for the company to build these things.
