Delta SkyMiles and GOL Smiles partnership is ending on April 1, 2020, the same date LATAM becomes a frequent flier partner of the US airline (read more here).
You can access Delta’s page for airline partners here.
Here’s information about the Delta & GOL partnership:
Note: On April 1, 2020, Delta and GOL will be ending their partnership and SkyMiles Members will no longer be able to earn miles, Medallion Qualification Miles (MQMs), Medallion Qualification Dollars (MQDs)* or Medallion Qualification Segments (MQSs) on GOL flights booked on or after April 1, 2020. Only Members who booked their GOL flight on or before March 31, 2020 will still be able to earn miles, MQMs, MQSs or MQDs.
GOL-marketed flights in the following fare classes are eligible for accrual based on the percentages in the table below, multiplied by the flight distance (as determined in Delta or the partner carrier’s sole discretion)1.
MILEAGE EARN THROUGH MARCH 31, 2020
On April 1, 2020, mileage earn will only be available to Members who booked their GOL flights on or before March 31, 2020.
It is good that SkyMiles members can earn miles for GOL flights taken on or after April 1, 2020, as long as they bought the tickets on or before March 31.
Delta and American are essentially swapping their Latin America partners. LATAM goes with Delta while GOL with American Airlines.
There is no comparison between these two airlines. LATAM is present in Brazil, Chile, Ecuador, Colombia, and Argentina, while GOL is a Brazilian domestic airline with few international flights.
