I need to fly RDU/FLL/RDU next week, down on one day, back on the next.

DL has 5 fares to choose from, WN has one. The WN fare is $5 more then DL's cheapest fare but is fully refundable. Since I do not know if I may have to stay an extra day, yet another no brainer. Keeping it simple or going out of business... DL does not need to fix anything, the board of directors must go.
