Guru’s Wrap-up
Head to Southwest.com before the clock strikes midnight (Pacific Time) on April 24 to grab these chap fares. The best deals are snatched up fast, so book sooner than later.
On May 28th Southwest will start charging for bags unless you have status, a Southwest card, or pay for more expensive fares. But if you book before that date, you still get two free checked bags.
This is also a good opportunity for those who have already booked upcoming flights with Southwest. The airline makes it easy to rebook. So you should always double check pricing for your flights and re-book if you see a price drop.
