We will be traveling Santiago Chile to Sao Paulo Brazil in Economy on Latam Airlines Brazil and then on to Atlanta GA in Business and on to SAN in Business in February (50th wedding anniversary cruise return). on Delta. Flights are on a single record locator.

Do we get free luggage (including our economy leg), do we get in a special line at the AP for the economy leg, will be get club rights before economy leg in Santiago (if so which)?

Thank you.
