Yes. Also, you get refunded the difference if you switch from a layover flight to a nonstop flight. I believe it's $5 per leg of the flight, so $5 for a nonstop flight, $10 for one layover, etc. Sometimes they'll add flights as they get closer to the date or if I originally book a layover flight because it's the lowest point cost and then a nonstop flight comes down in points and I book that, I get my $5 back.
