Nothing earth shattering. Some would argue that it provides an extra 2.8 days/month per pilot on that schedule, and if no one bid it, company would be forced to consider recalling pilots.
The fact is the schedule can only be reduced up to 10% every bid period, so it would take years for that schedule to go away, even with 100% participation.
Before anyone gets all hell bent over the GLC folks, read section 19.9 of the CBA regarding international flying. Management refuses to use that provision, and instead elects to pay those folks extended days. And if you think airlining crews around the planet makes more economic sense, I'm just glad you're not in management, or none of us would have a job.
