You're saying that doing it this way makes sure that it's a person that is coming in new for the very first time?
Yes.
What if they haven't been with us for a long while, wouldn't I want them to receive the welcome email again?
Well, that's up to you. But I wouldn't call it "Welcome" and they wouldn't be "New". 
Hi Sanford,
I kind of switched things up to the below. Can you let me know if this looks correct? I essential removed the travel type filter from the smart list and instead did it in the flow.
