So at Mesaba, if on a 1.5 or 2.0 hour call out, they can't call you 5 minutes before the end of your shift and tell you that you have to do a flight in 1.5 or 2.0 hours for an overnight somewhere? Basically if they don't call you in your callout time prior to your duty off time they can't use you anymore?

Just asking because at my prior airline they would call you up to a minute before your duty off time and extend your reserve shift to whatever they needed to get you to do a flight, up to a total of 16 hours on reserve of course...
