Have not traveled commercially for many years and have always traveled either private or by car. Try as I might to arrange an alternative, circumstances are going to require two domestic commercial flights in the next several weeks. What's the low down on airports these days? Has security changed much from a decade ago? Is it better to check or carryon luggage with wuflu rules? Do I need to be concerned about getting kicked off a flight for not wearing a mask in firstbuisness? Any other tips are appreciated.
