I had to fly home from my sister's house in July. It actually was not too bad, but it wasn't like a holiday or anything. I wouldn't want to fly at like Christmas or something.

Airports were VERY quiet. It was no problem staying distanced within the terminals. The airline I used kept the middle seats empty. Everyone had on masks and was as careful as you can be in a small space. The only time I felt crowded was when we landed. Why do people all stand up in the aisle at the same time? I just remained seated until people were moving and more spaced out.
