Thanks for the insight wiggy. Now that you mention it, I've had some sort of maintenance note requesting a procedure be done before going ETOPS to raise the dispatch to 180 minute rule. Since we were already airborne, we got a redispatch for the 180 minute alternates.
Also, now that I look at it, Frobay may be far enough north that you could get to ZRH on a Blue Spruce routing without ETOPS if needed.
