I used to take same day round trip flights all the time. Isn’t it normal for business travel? I could leave home at 7am, fly to stinky Sydney, meet my customers, and be home again by 7pm.
Yeah I don't think anybody would ever get on your case about tight turns that were possible. The problem only occurs when you book flights with segments that directly conflict with each other. Or depart within minutes of each other despite their origins being thousands of miles apart.
