“Migrant travelers”?
I traveled internationally a lot before I retired.
If I needed a visa, I applied for one. Never had a problem. No visa, lotsa problems.
So the people Naomi the Non-American is talking about are not “migrants”, they “invaders” and “trespassers” which is what people are when they enter someone else’s territory without permission.
And their relatives are the problem, because they encourage it and harbor them.
All I can say is good for Delta! I don't need to be sharing a cabin with some covid inflicted illegal alien.
