I'm surprised your friend would think about traveling to see a new grandbaby in the midst of all this, especially to Seattle where she could pick up something on her way there and pass it on. BUT, that is just me.
My daughter came through Seattle end of February and didn't get it. This was way before any travel restrictions or anything really. She was out there on a visit to see the school for grad school. Tried to get tested and nada (she had zero symptoms then or since). Would have been nice to know if exposed etc.
As far as travel plans:
We are supposed to fly out of New York on May 14th, condo outside Paris for a week, with 3 days at DLP and then several days in Paris at AirBnB(which I haven't booked yet-held off in Jan/Feb when all this started). Tickets purchased for travel to Paris only. Again held off on flights to/from NYC as all this was starting when I started looking. Flights home from Paris/NYC haven't changed (if anything a few bucks cheaper).
With all the flexibility in flight changes I am planning on booking the flights to/from NYC by end of month (generally the deadline to change any ticket booked this month for travel later) as flights are now dirt cheap. And I've retraded the condo for 2 weeks later (still have 2 more trades as I purchased the Etrade flexibility when I did the first booking-something I never did before, but glad I did now, through II), will move the Disneyland Paris reservation (no charge for change fee or package and will keep the same package even though choosing more expensive date). Will probably book AirBnB too for the later dates, but only one with good cancellation policy. I figure nothing to lose really-even if restrictions stay or extend I anticipate the airlines etc will extend the change flexibility too.
To sum up-yes still planning travel just pushed it out 2 weeks from original travel date-from originally ~7 weeks out to 9 weeks out. Seems 6-8 weeks was estimate (as of last week) so hoping this gives me more of a cushion.
