So I am flying from MSY-ATL-SAT on Sunday. I managed to get the last seat on the MSY-ATL flight on an B fare (booked one way, last minute ticket) and due to Spring Break, I am thinking the flight will be oversold. I was wondering if I take a VDB, will Delta make the proper arrangements to get me seats on a later departing ATL-SAT flight. That is an A fare on the 5:55 departure. Any thoughts about if I should take the VDB if offered?
