I am glad SWA finally came forward and also agreed to mandate mask and/or face coverings, leaving middle seats empty, and spacing every other row and seats for social distancing. Now I am even a bigger fan that it sounds as if all the airlines are also in full support of checking the temps of all passengers, employees and flight crews of all on board. Anyone with the recommended 96.9 CDC temp should be denied boarding, no questions asked, no if's and's or but's. I know this article just reads as supporting but usually once all airlines are in agreement, hopefully it will be made mandatory for all.
