I've been waiting for Southwest to extend as I'm going the end of August. Came home to the email and booked fast. Some of the cheaper flights are going fast. I booked the 4 of us nonstop out of Providence for $79 each way plus their fees and taxes. It came to $700 total. Still higher than I've paid other years, but not bad. Got the times I wanted too. So if you were waiting, book now!
