Ironically enough, the trip that stemmed my original question in this thread was supposed to happen *last year* but I pre-emptively took a test a few days before our departing flight. Due to work I am exposed to Covid daily and while I wasn't sick I just had something in the back of my mind telling me to get tested, and sure enough I tested +. Never did really get sick but boy was my wife mad when we had to cancel our trip!

BTW: thank you to everyone for the replies!
