We used to drive and spend night in Gulfport or Biloxi the night before the cruise but last month we flew from Chattanooga on Delta the morning of the cruise. We booked it through Carnival Fly2Fun since it was actually cheaper than booking through Delta and we didn’t pay for the flights until we paid for the cruise. We had no problems with any of the flights. We’ve booked the same cruise for May and plan to book again through Fly2Fun.
