This may be more of a Latam question but wondering if anyone has guidance on mixing cabins. Under the new system, I should be able to add a connection onto my IPC-SCL flight (business class, 35k miles) but most of the destinations I am looking at only have single cabin service. Can I book IPC-SCL (biz) and SCL-MVD (eco) for 35k, taking the downgrade to Y on the SCL-MVD segment? It would save me 7.5k x 5pax so not a bad deal if possible. It clearly doesnt work online, wondering before I call in whether anyone has done this under the new charts?
