Q. What’s the difference between “nonstop” and “direct” flights. I seem to see the terms used interchangeably.

A. “Nonstop” means, not surprisingly, that the flight lands just once (at your final destination). “Direct” means that the flight stops along the way, but there’s no change of planes. We also see the two terms used as if they were the same thing, and we're happy to clear up the confusion.
