Wikipedia still has a picture of a ticket printed on old style stock here. The problem is that they're just feeding blank white stock into the printer, but whatever is doing the formatting was told it's on standard stock. The most probable outcome, given how institutions work, is that AS will manage to update the format so it makes sense on blank stock, and someone at the airport will put real ticket stock in, and we'll get a post in a couple weeks from someone who has an unreadable boarding pass because it's the new format on pre-printed stock
