Delta Air Lines and United Airlines both operate hubs at one end of this route, so nonstop or single-connection service is usually available, along with American Airlines, Southwest Airlines, and Alaska Airlines. Our agents can book any of them and compare fare classes side by side.
Covering 3,305 miles, the flight runs around 6h 56m nonstop. On sectors this long, one-stop itineraries through a hub are often priced well below the nonstop and add only a few hours; the agent will show both.
Southern departures see their highest fares over spring break and the winter holidays; late summer and the weeks after Labor Day typically bring the lowest prices.
Midweek travel almost always beats weekends on price here. If your dates are flexible by a day or two, tell the agent; shifting a Friday departure to Thursday or a Sunday return to Monday is the single most reliable way to cut the fare.
For domestic travel, booking three to eight weeks ahead usually captures the best price. Inside two weeks, fares climb; more than four months out, airlines have not yet released their cheapest inventory.
