Received an email from Southwest with the following wording-
We know how important it is to experience new places with family and friends, which is why we created the unparalleled benefit of Companion Pass2. To continue offering unlimited flights for Companions3 when flying with their Companion Pass holder, we're increasing the points required to earn a Companion Pass from 110,000 to 125,000 beginning January 1, 2020.
Don't worry, for those earning a Companion Pass through flights, you can still earn yours by flying 100 qualifying one-way flights. If you are currently working toward a Companion Pass through points, you can still earn it with 110,000 qualifying points through December 31, 2019. Your Companion Pass benefits will begin the day you earn it and continue through December 31, 2020.
