Because it's not the same process. QS is automated, not an IA free for all, side deals will be pretty much eliminated, contractual seniority gets reestablished, and now you have a choice on whether you get phone calls or not (which wasn't the case with IAs). And they have to actually identify the skipped pilot before they can cover the trip, now who knows if people are getting paid for being skipped.

And reminder, what they are doing today is not an IA. They are just using that as a placeholder because they have no other way to code it. An IA per the contract is not a profer and you have to fly it if called. I think a lot of people would be responding differently if this is what was actually going on.
