Flight LA500,SCL-MIA March 11th, I was in seat 4 and there were 6 seats available on the list. The T-12 seats were reduced to 4. When I boarded, SS told me, "No one got an upgrade." all the seats went to bidders.
On LA flight 503 MIA-SCL, of the 6 available seats, T-12 4 seats available. At least 4 Signature members were able to get upgrades. 38 people applied to an upgrade:There were 14 Signature members on the list, plus 8 more Black members, and so on. At least I was able to get seat 12J, which had plenty of space

Since the 787-8s were remodeled, the number decreased from 30J to 20J, making very difficult to get an upgrade, especially on routes like MIA, BOG, MEX, JFK, GRU, and LIM from SCL, also with the high priority of bidders is become difficult to score a upgrade in routes within South America.

SS agent told me that several Signature members have migrated to other airlines because of all the changes LATAM have made.

Since the changes in the middle of the year i decided to stop flying in latam and be more a freelance traveller, at least for me, no more Signature,. I prefer to switch to OneWorld or Star Alliance airline member for the benefits in other airlines.I wish good luck to the all Signatures who will follow this year!
