I have a reservation this Friday to PHL > ATL> HOU and Sunday HOU > DAL > PHL. When I checked my reservation in the SWA app, there is a red banner that says "Important: You can change your flight". When I click on it, I get a message all in red that says " You may change your travel date/time at no additional cost. "Circumstances beyond our control (weather, etc.) are creating disruptions to our schedule and a flight(s) on which you are currently booked may adversely me affected." When I look at my reservation on the Southwest web site, it does not show the banner or anything about changing my flight. My flights are still showing on-time both in the app and web site. I have never had this happen before with Southwest. Why are they offering me the option to change my flight?
