With that logic, you could argue we don't get paid when we fly on reserve, either. If you're arguing that we don't accrue credit hours when sitting ready reserve, that's true of course. But on reserve it's generally irrelevant -- whether you are called in to fly, or called in to sit airport standby, you are highly unlikely to break the 75 hours guarantee. So both scenarios have the same result -- you could be called in all but 11 days of the month. You will be paid 75 hours. Yes, flying accrues credit hours, while ready reserve does not. But that's a technicality when neither case leads to more pay (i.e. breaking 75 hours).
