Thanks for all of the comments.
Here's an update.
I talked to my sister today, she is not interested at all in going. Mom is in the same boat. So that part of the trip looks as if it's off.
I am planning to go Nov 8th.. the logic is I do think it's safe and won't worry about it. I plan to visit the British Museum while I am there.
So there we are. It's a comprise.. sister won't go, but I will.
Maybe Vienna in the spring.
Thanks again for all of the comments and thoughts.
Anyone want to make a run DFW-LGW Nov 8th.?
Or is there a better place to go for $450?

This has been helpful.
