Segment pay, or historical block pay sucks and should go away. Hopefully the new contract will accomplish this. A pilot's hosing by segment pay can vary a lot depending upon the domicile. Some airports are much more delay prone than others. In DEN we were an hour late departing due to congestion at the de-ice pads. In PHX I have not yet seen a huge difference between my actual and the historic block times.

At other airlines, if a flight is delayed due to maintenance, does pay start at scheduled out time or actual out time? A buddy of mine works at a block-or-better airline. While in ground school and sim training he was not paid. He received $200 per week per diem. How long will it take for his block or better pay to make up for the fact that I was paid a 70 hour a month guarantee from day one?

As bad as segment pay is, the actual differences in earnings depend upon a lot of work rules. Mesa is not necessarily worst in each rule.
