I can buy a main cabin MIA-UIO RT on LATAM for about $400, or the same LATAM ticket from Delta for $585. But I note that if I add a piece of luggage to the LATAM ticket, it prices at $585. So I guess the Delta price reflects a LATAM ticket with one bag?
As for upgrades (I am Plat), LATAM has economy and "premium economy" but no C+. Would i be eligible for an upgrade?
Thanks
