The big mistake on her part was not letting you know this well in advance, which it sounds like she owned.

I would have been comfortable with this. In fact, more than comfortable -- I prefer people who are cautious around covid.

That said, I think there are alternative protocols that could have worked for you both. The rapid tests are less sensitive to omicron, so there's likely a few days where you could be infected, and infectious, but test negative on an at-home covid test.

I talked about this with my doctor in detail, and he agreed a protocol like this would be far more safe -- AND give you advance knowledge before you fly. Let's say you are flying on Friday and sessioning on Saturday.

Thursday: get a PCR test at a lab. These tend to be coming back same-day, or next-day at worst these days.

Friday: Fly out if your PCR test is negative

Saturday: session, since your PCR test is negative.

But what if you got infected while flying Friday? There's no evidence that you can be infectious within 24 hours.

Anyway, my doctor gave me the thumbs up on this protocol, and says it is far better than a rapid test since the rapid tests need the infection to progress so far with omicron. In fact, he told me if Thursdays PCR test came back negative, no reason to do a rapid test at all
