As someone who has endured several flights over the years seated next to someone who is clearly toxic, I'm amazed that most airlines haven't resorted to temperature guns to reduce the number of clearly sick travelers from planes. And this goes way previous to COVID.
I still think they should (and have seen a few regional carriers do this) but you gotta love the ingenuity of whoever figured out that dogs can sense sickness in humans.
Temperature guns and dogs. Simply love the concept...unless you're too self-absorbed to care about your fellow passengers.
Just sayin.
