A/C was not working on the ground so it was 110 degrees on the plane when we boarded and we sat there for almost 40 minutes because Austin’s gate system has not kept up with growth. Not Alaska’s fault 100% but it was miserable.

A/C was not working on the ground so it was 110 degrees on the plane when we boarded and we sat there for almost 40 minutes because Austin’s gate system has not kept up with growth. Not Alaska’s fault 100% but it was miserable.
