Hi,
Not a Pinnacle guy but Ex mesa so I think that qualifies me for recognizing a screw job.
It looks to me that the 15 minutes reduces your call out time to 75. Another words to pressure you to answer it when it rings they are taking the 15minutes. From a scheduling stand point I see why they want this but I think its a play for the JO handbook.
I'd tell crew stalking when you talk to them that you'll hustle but it will be about 90 minutes. Be nice about it and when they say "Ok, thanks" its on the tape.
Of course you know the rule, you could be standing at the departure gate and its "90 minutes"
Better to have a Pinnacle pilot chime in though.
Edit: Go with CDT on this. Its not a grudge, point is that if you can make it consitantly in 60 minutes guess what happens next time Section 6 negotiations come around. You bet, 60 minute call outs. I am not saying don't hustle just don't give them the impression that 60 minutes is good enough.
