Lots of LA experience, only one trip as a PM. The short haul was in the Y cabin and in a saver Y award code. Preferred (but not best) seat selection after booking. At check-in, I was in Zone 2, companion in Zone 5. At airport, both in Zone 2.

System wanted to charge me for luggage, even on a premium J segment. At airport, not an issue.

Note - LA will not check bags through on separate PNRs for anyone, except perhaps under extra special circumstances that are kept in a special safe at Pudahuel. They didn't do it for a OW premium pax (as part of OW), they don't do it now, and it causes quite a bit of tsuris.
