I took my monthly precautionary Covid-19 test on Tuesday of this week (Nov 10) and got a positive diagnosis two days later (Nov 12). I had taken a UA flight on Nov 8, two days before the positive test. I immediately emailed UA with my flight information, seat number, etc., and received a response that said (paraphrasing--I have the full e-mail if anyone is curious about the precise response): "We're very sorry and hope you recover quickly. It is up to the CDC to contract trace." This struck me as odd because the CDC doesn't know my positive status (as far as I know) or my flight history. While I realize we are probably well beyond the point where contact tracing is effective, I would have thought that in this scenario, as a courtesy, UA would at least reach out to the passengers in the rows immediately around me and informed them of the possible exposure. I know I would have liked to know had I been one of these passengers. But UA seems to have washed its hands (no pun intended).

Btw, I am asymptomatic and feeling fine (knock on wood).
