I'm wondering why the bad margin. Broad strokes.

Are the a320(+/-1) all old and needing a super high level maintenance? And this quarter they lucked out not needing parts? Or have they been aircraft-of-theseus's, so all new, except for the airframe proper?

Or just a attribute of a big country and with more small outports domestic and internationally, with a still a larger (but low population) central core, than just about anyone else?
