It is a pain but number 4 for sure. I was due to fly from Canada to the UK via the US for a close family wedding. We had to pull the plug 2 weeks ago when it was apparent we wouldn't be able to fly even if we wanted to. The wedding itself was postponed a week later due to limits on gathering size. Rescheduled for August but my gut feeling is that it's 50/50 whether we'll be able to travel for that either. Canadian authorities subtly suggesting at least till the end of June through numerous sources at present.
If my wife's elderly mother in the UK passes we would be unable to travel for the funeral either. Heartbreaking but that is the reality at present.
