So I've been looking around for information for the last week or so and apparently if both airlines are on oneworld they treat it as one ticket?
e.g.

I'll go ask LAN as well but does anyone know about this?
I've checked my flights and LAN does offer them on one PNR, so according to them the connection is possible, but below MCT by 5mins
However I'm not sure if I can check my bags straight through since it's a international to domestic connection. Can anyone shed any light on this?
