It may be a good idea but we had zero symptoms before day 7 (we arrived a day early). So we would have tested negative.
I think that
@tursiops may have been referring to each flight, not just the outbound. You were symptomatic before boarding. Did you mask during travel? You might well have had a positive antigen at that point.
I certainly understand all of the complications involved in a positive test before a return flight home. The US just dropped that requirement. No one wants to delay their return for 5-10 days, for many reasons. I get it. But it's still better not to spread COVID around if you can avoid it, for many reasons beyond the scope of this thread.
I don't mean to oversimplify the decision making process involved. I understand that it's complex, and I deal with this regularly these days.
But the idea that there is some eternal COVID truth that we can discover and adhere to in all situations is a fantasy. As variants come and go, as outbreaks wax and wane, there are going to be different recommendations and best practices for each time.
Lots of performative BS out there. "Before you said to mask, but now you are saying not to, which is it?". It's not about catching someone in a "lie" or proving who was right and who was wrong. If you are approaching this in good faith, you need to keep an open mind, watch the data and be flexible.
