While I love Southwest I am starting to have a few frustrations with them. This summer we were booked on 9:45 return flight home from a vacation and a few weeks before the trip we were notified that our flight had been changed to 5:15. 4.5 hours is quite a lot when you are visiting a theme park and had made reservations that have to be cancelled last minute due to the flight. That was the most extreme change but the last 3 flights have all seemingly had smaller changes leading up to them (not day of weather related I totally can understand that). Overall we do keep going back for the affordability of their flights and the kindness of their staff.
