I think you just created the master thread! There’s one about the -700’s, but I think that they’re all done now. I’m sure, for now at least, it’ll have less traffic than the Airbus thread, just because reconfiguring the 800/900’s is a bigger task, with less customer impact, that hasn’t really started yet. But it’ll be good to have a thread for chatter about these reconfigs.
As for an outside resource, the best one I know of is
