Bags don’t fly free with Southwest any longer. In March, Dallas-based Southwest Airlines announced a major change to its longstanding bags-fly-free policy: checked bags, for the most part, would no longer fly free.

Starting on Wednesday, the Dallas-based carrier will charge customers $35 for their first checked bag and $45 for their second checked bag. The bag fee change will also apply to existing flight itineraries changed on or after May 28, Southwest confirmed to "Good Morning America."

Southwest Airlines ends free checked bags, introducing fees starting May 28, with exemptions for certain members.
