These discount deals from Delta, are targeting traditional American Airlines hubs to this sandy Atlantic archipelago. Daily flights at this price start in late July and are valid for travel through the end of August with returns in early September available. No minimum stay required.
As an example, searching on the Delta, I found seats departing PHX on Wednesday, August 15, and returning from NAS on Friday, August 24, 2018. Fares are wide open at this price and relatively easy to find on any booking site.
